Sometimes the chat attitude ability resemble as a safe norm. So, abounding bodies would like to do things in a acceptable manner. But, abaft every benefit, there is a loss. Coming to the allotment of trees, we fabricated affidavit from bulb artificial fibers. These are calmly destroyed by either aqueous or fire. By accomplishing this, the papermaking industry consumes a ample cardinal of accustomed copse and appropriately causes austere ecology problems including boundless deforestation and pollution. So, we alleged it the acceptable action of papermaking. In appliance of the built-in flammability of organics and aspersing the furnishings on the ambiance and creatures, biocompatible ultralong hydroxyapatite nanowires are an ideal architecture actual for the fire-resistant asleep paper.
New Fire-resistant Asleep Cardboard
The Awful Adjustable and Non-flammable Asleep Cardboard is fabricated from ultralong hydroxyapatite nanowires. The new fire-resistant asleep cardboard was apparent by the analysis accumulation led by Prof. Dr. Ying-Jie Zhu from Shanghai Institute of Ceramics, Chinese Academy of Sciences (P. R. China). The new affectionate of the fire-resistant cardboard can be acclimated for press and writing, and is able for the abiding and safe accumulator of information, such as athenaeum and important documents, alienated actuality destroyed by fire. This apparatus provides a able bend for the fire-resistant asleep cardboard as a accessible acting for the acceptable artificial paper, which has acquired austere ability and ecology problems.
Hydroxyapatite is a accustomed mineral, and is the capital asleep basic of animal cartilage and teeth. The animal cartilage contains about 70 wt. % hydroxyapatite; tooth apply has added than 90 wt. % hydroxyapatite. Hydroxyapatite exhibits accomplished biocompatibility, ecology friendliness, high-quality white color, high-temperature resistance, and accomplished nonflammability. Therefore, it is an ideal raw actual for architecture new fire-resistant asleep paper.
However, a abundant claiming arises: hydroxyapatite abstracts usually accept aerial brittleness and poor flexibility, authoritative them difficult to accomplish bendable fire-resistant paper.
How to break this problem? The Zhus accumulation begin that ultra continued hydroxyapatite nanowires with lengths of added than 100 microns accept acceptable adaptability and can finer break the botheration of aerial brittleness of hydroxyapatite materials.
However, the amalgam of ultra continued hydroxyapatite nanowires is a big challenge. The Zhus accumulation developed the calcium oleate forerunner solvothermal adjustment for the amalgam of ultra continued hydroxyapatite nanowires with lengths up to several hundred microns (the best breadth is alike aing to 1000 microns). The as-prepared ultra continued hydroxyapatite nanowires accept diameters of about 10 nanometers, which is about 10,000 times abate than the array of a animal hair, and the nanowires can bend artlessly with a aerial adaptability (Figure 1). However, this constructed adjustment uses an oleic acid/ethanol/water alloyed acknowledgment system. Then, the aggregation has developed a new bargain amalgam adjustment appliance an environmentally affable distinct baptize acknowledgment system, and the aqueous abeyance absolute ultra continued hydroxyapatite nanowires has a aerial whiteness (Figure 2), abundantly abbreviation the bulk of booze used, and does not crave use of oleic acid. This alertness adjustment is environmentally friendly, and the actinic raw abstracts are common, readily available, and inexpensive, and no baneful and adverse substances are produced.

Figure 2. An aqueous abeyance absolute ultra continued hydroxyapatite nanowires able by the calcium oleate forerunner hydrothermal method.
In addition, the scaled-up amalgam of ultra continued hydroxyapatite nanowires is approved with an alter with a aggregate of 10 liters and alike a beyond calibration with a aggregate of 100 liters.
The Zhus accumulation has auspiciously developed a new blazon of fire-resistant asleep cardboard based on ultra continued hydroxyapatite nanowires as the architecture material, which has aerial biocompatibility, is environmentally friendly, and artificially actinic afterwards arresting adored accustomed assets such as forests. The new fire-resistant cardboard is awful flexible, exhibits high-quality white blush afterwards bleaching, and accomplished attrition to aerial temperature and blaze (Figure 3). The new fire-resistant cardboard does not bake in blaze alike back actuality acrimonious to red heat, and can bear aerial temperatures of 1000 C or higher; while the accustomed cardboard is austere to ash afterwards acknowledgment to blaze in a few seconds. In addition, the new fire-resistant asleep cardboard has above achievement in attrition to mould compared with the acceptable paper.
Figure 3. The new fire-resistant cardboard exhibits accomplished attrition to aerial temperature and fire, it does not bake in blaze alike back actuality acrimonious to red heat, and can bear aerial temperatures of 1000 C or higher.
Through a ample cardinal of experiments, the aggregation explored and optimized formulations for the ultra continued hydroxyapatite nanowire abeyance and asleep adhesives, as able-bodied as the alertness technology for the fire-resistant paper, which abundantly bigger the automated backbone and added backdrop of the fire-resistant asleep paper. The fire-resistant cardboard can be acclimated for autograph and blush printing, and is accepted to be acclimated for abiding safe accumulator of books and important abstracts such as athenaeum and certificates. It additionally has abounding added uses and has acceptable appliance affairs in abounding fields. The accomplishment action of the fire-resistant asleep cardboard is environmentally friendly, does not adulterate the environment, and has acceptable automated appliance prospects.
The fire-resistant asleep cardboard bedding with a A4 admeasurement (21 cm x 29.7 cm) accept been auspiciously developed, which can be anon printed with a bartering colour printer, and the press aftereffect is acceptable (Figure 4). The aggregation has additionally auspiciously able the fire-resistant cardboard with a A3 admeasurement (42 cm 29.7 cm).

New Waterproof Fire-resistant Asleep Cardboard
Subsequently, by assuming the anatomy and aftereffect of lotus leaf, a new affectionate of awful flexible, cool berserk (waterproof), and fire-resistant layered asleep cardboard has been auspiciously able by the aforementioned aggregation appliance ultra continued hydroxyapatite nanowires as a architecture block afterwards the apparent modification with sodium oleate (Figure 5). During the exhaustion filtration, ultra continued hydroxyapatite nanowires accumulate into a absorptive hierarchical arrangement with a layered anatomy and anatomy the awful flexible, waterproof, and fire-resistant paper. The layered anatomy can decidedly advance the attrition to the automated accident of the as-prepared waterproof and fire-resistant paper. The cool berserk acreage of the waterproof fire-resistant cardboard has a aerial adherence and can be able-bodied preserved alike in the aerial temperature environment. The as-prepared waterproof and fire-resistant cardboard shows accomplished non-flammability, aerial thermal stability, accomplished aqueous abhorrence to baptize (Figure 6) and assorted bartering drinks. The waterproof fire-resistant cardboard has a acceptable self-cleaning function, and dust and contaminants on the cardboard apparent can be calmly done abroad by water, thereby accomplishing self-cleaning of the surface. If it is acclimated for amphitheater billboards, it can automatically apple-pie the dust by rain, alienated the agitation of chiral cleaning, and blurred cost.

A new affectionate of awful flexible, waterproof and fire-resistant layered asleep cardboard able appliance ultra continued hydroxyapatite nanowires afterwards the apparent modification with sodium oleate. Baptize (dyed with methyl blue) has a acquaintance bend of added than 150oC on the apparent of the waterproof fire-resistant paper, and baptize cannot be captivated into the paper, but forms all-around baptize aerosol rolling on the cardboard surface.
Figure 6. Back the waterproof fire-resistant cardboard is absorbed in the dejected ink and the apparent of the cardboard is not attenuated with baptize or dejected color.
Moreover, the abeyant applications of the waterproof and fire-resistant asleep cardboard accept the able qualities as a awful able adsorbent for oil/water separation, fire-shielding protector, and autograph paper.
Various Types of New Fire-resistant Asleep Cardboard and Their Able Applications
Up to now we acquainted that the fire-resistant asleep cardboard ability alter the combustible acceptable cardboard in the future. Now acquisition out the added features. The hydroxyapatite nanowire cardboard with accomplished fire-resistant and adiabatic backdrop is awful accepted in assorted high-temperature applications.
The Zhus accumulation has additionally developed abounding added types of the fire-resistant cardboard based on ultra continued hydroxyapatite nanowires for assorted applications, such as high-temperature-resistant characterization paper, fire-resistant calligraphy and painting paper, antibacterial fire-resistant paper, bright fire-resistant paper, multi-mode anti-counterfeit fire-resistant paper, electrically conductive waterproof fire-resistant paper, catalytic fire-resistant paper, waterproof alluring fire-resistant paper, automated blaze anxiety fire-resistant wallpaper, high-temperature array separator, fire-resistant wrapping band for optical (electric) cables, high-efficiency clarify cardboard for amoebic pollutants/air PM2.5/anti-fog mask/air purifiers, biomedical cardboard for cartilage birthmark adjustment and bark anguish healing, and accelerated analysis paper, etc.
So, a anarchy may appear through this new discovery, which will abbreviate the ecology abuse and cautiously assure paper-based books and documents.
