硅基乳液凝胶的制备及应用
Research and application of silicone-based emulsion hydrogel
摘要
Abstract
This study designed a half-oily liquid hydrogel(HOLH).The silicone oil molecules in HOLH can escape from the emulsion droplets and,after photocuring polymerization and gelation,freely infiltrate into the hydrogel with composed of amphiphilic cross-linkable organic polysiloxanes.This emulsion gel achieves achieved a sebum-like secretion function and a lubricating surface layer through uniformly distributed immiscible and mobile silicone oil molecules.Compared with traditional hydrogels,HOLH exhibits a lower water evaporation rate(the relative weight increases from 45％to around 75％when exposed to air for 7 d)and excellent liquid repellency(sliding angle＜10°),effectively blocking complex liquids such as water,oils,and blood.In addition,the polyaniline nanoparticles dispersed in the emulsion gel skeleton give HOLH excellent pressure sensitivity,making it have both antifouling properties and sensing functions.This strategy provides new ideas for regulating the interactions between hydrogel components and silicone oil molecules,and for designing interfacial functions and biomimetic materials.关键词
