Polylactic acid based Janus membranes with asymmetric wettability for directional moisture transport with enhanced UV protective capabilities.

ABSTRACT: Efficient directional moisture transport can remove excess sweat away from the human body and keep the body dry; fully utilizing this functionality to improve the wearing experience is urgently needed in the area of functional textiles. Herein, a facile strategy is used to design an eco-friendly and biodegradable PLA membrane with enhanced directional moisture transport and UV protection abilities. The PLA-based Janus membrane with asymmetric wettability is fabricated via sol-gel and electrospinning methods. Titanium dioxide nanoparticles (TiO₂) were anchored onto the surface of the PLA fabric during the TiO₂ sol-gel fabrication process using polydopamine, forming superhydrophilic TiO₂@PDA-PLA. Then a thin PLA fibrous membrane layer showing hydrophob
