“…This composite was recently successfully synthesized and exhibited excellent performance when applied in powder form to photocatalytic degradation of methylene blue in aqueous media, as reported in our previous work [7]. In another work [8], the same composite applied to cotton fabric exhibited superior fire-retardant behavior decreasing flame propagation due to its mineral nature when combined with phosphorus and nitrogen compounds. The present work shows that our composite also exhibited antimicrobial activity in addition to the photocatalytic and fire-retardant properties.…”

“…The reason might be attributed to the boric acid/borax contained in C1, C4, and C7, which had better flame-retardant capabilities and could form a glass-like coating film covered on the surface of the coatings to block the entrance of oxygen and heat at higher temperatures [52][53][54]. Moreover, some researchers have proven that UV absorbents, including nano-SiO 2 , nano-TiO 2 , and UV1130, could effectively reduce the pyrolysis of coatings [55][56][57]. Among them, C4 had the best stability, because the network-like nano-TiO 2 covering the surface of the carbon layer enhanced the thermal stability of the coating.…”

Boron-Based Mildew Preventive and Ultraviolet Absorbent Modification of Waterborne Polyurethane Coatings on Laminated Bamboo

In order to improve the outdoor exposure performance of laminated bamboo, boric acid/borax and UV absorbents, including triazole (UV1130), nano–TiO2, and nano–SiO2, were used to modify waterborne polyurethane (WPU) coatings, respectively. The physical and chemical properties of the coatings with and without modification were evaluated by adhesion strength, contact angle, wear, and temperature-resistance experiments. The antimildew properties of the coatings were evaluated by the bacteriostatic zone method, and the pyrolysis characteristics were investigated through TG–FTIR analysis. The results showed that, when compared with the unmodified WPU coating, the coatings with different modifications had stronger wear resistance; the mass loss of the best C4 coating was only 0.0078 g, which was 0.0203 g less than that of the unmodified C0 coating. However, when compared to the unmodified coating, the wettability of the modified coating increased to different degrees, and the contact angle of the C4 coating with the most obvious effect was only 36.50°. During the curing process of the modified coatings, the UV absorbents and boric acid/borax would interact with the C–N, C–O, and C=O bonds in the coating and change the molecular structure of the WPU. The thermal stability of the coatings with different modifications was enhanced. The best result, a 76.27% weight loss, was observed in the modified coating with boric acid/borax and 1.0% nano–TiO2. Different modified coatings had a certain degree of control effect on Aspergillus Niger, and the reason for this was considered the combined effect of boric acid/borax and UV absorbents.

“…This coated layer does not propagate flame when it comes to the effect of fire and provides self-extinguishing characteristics immediately after the heat source is removed. The functionalization of the fabric reduces the thermal degradation of the cellulosic fibre by 41% [64]. Insignificant resistance against the washing of cellulosic fabric is observed whereas mechanical strength of the fabric is almost retained.…”
