Thermoregulation is an essential function of the human body for adapting to surrounding temperature. Stimuli-responsive smart textiles can provide effective protection skin temperature from a continuously changing environment. Herein, we develop textile based on shape memory polymer (SMP) fibers adaptive regulation IR and water transmission skin. An SMP fabricated with hierarchical micro/nanoporous structures enhance thermal insulation performance, silver nanowires are coated one side asymmetric reflectivity hydrophilicity. The porous shows great tunability wettability by deformation recovery structure in response stimuli. degree controlled 65.7% original value, surface hot plate successfully images due reflectivity. Additionally, directional transportation droplets be switched on/off according textiles, which employed sweat removal This IR- water-gating feasible strategy protecting external environmental changes.
