Abstract

Encapsulation of triethoxyoctylsilane-modified SiO₂/TiO₂ hollow particles (M-HPs) in polyacrylonitrile (PAN) nanofibrous membranes achieves robust ultraviolet (UV) resistance (UPF value of 1529.31) and broad-spectrum antibacterial effects, surpassing the performance of commercial solid TiO₂ nanoparticles.
