摘　　要：Public safety incidents caused by bacterial infections have attracted widespread attention towards antibacterial textiles(fibers,fabrics,etc.).Nevertheless,it is still challenging to efficiently load inorganic nano-antibacterial materials in polymer fibers.In this work,zirconium phosphate(ZrP,layered micro-nano materials)was utilized as a micro-nano carrier.The octadecyl triphenyl phosphonium bromide(OTP)was intercalated between the ZrP sheets by the ion exchange method to improve the carrier-polymer compatibility and the antibacterial performance.Through in-situ chemical reduction,the ultra-small nano-sized cuprous oxide(Cu_(2)O<5 nm)was loaded on the outer surface of ZrP to realize the uniform and stable dispersion of the Cu_(2)O on the carrier and improve the antibacterial performance.The ZrP nanosheets loaded with Cu_(2)O and OTP(Cu_(2)O@OZrP)had excellent antibacterial properties,and the antibacterial rate against E.coli,S.aureus and C.albicans was more than 99%.The intercalation amount of OTP in Cu_(2)O@OZrP can reach 16%,and the thermal stability was excellent and a significant increase in the Zeta potential.Indeed,the decomposition temperature was greater than 350℃,which was suitable for high-temperature melt processing of polymers.Consequently,we prepared PET/Cu_(2)O@OZrP fibers using polyethylene glycol terephthalate(PET),which accounts for 70%of the total chemical fibers,as the fiber matrix.PET/Cu_(2)O@OZrP fibers exhibited excellent mechanical property and antibacterial performance when the content of Cu_(2)O@OZrP was only 0.2%.The antibacterial rate against five types of bacteria including super bacteria(MRSA,VRE)was more than 99%.
