PVA/(AA-co-AM)/LiTFSI复合离子导电水凝胶的制备及其性能研究
Preparation and Properties Testing of PVA/(AA-co-AM)/LiTFSI Composite Conductive Hydrogel
摘要
Abstract
In this work,a series of PVA/(AA-co-AM)/LiTFSI composite ion conductive hydrogelsbased on PVA,AA,AM and LiTFSIwere pre-pared by free radical polymerization,using potassium persulfate(KPS)as the high-efficiency initiator,and theswelling properties,thermal stabili-ty,mechanical propertiesand electrical properties of composite conductive hydrogels were studied.The results showed thatthe amount of polyvinyl alcohol had little influence on the thermal stability of thePVA/(AA-co-AM)/LiTFSI composite ionic conductive hydrogel,and the thermal de-composition temperature of the prepared hydrogelreached about 210℃,indicating that it had excellent thermal stability,but the swelling proper-ties,tensile properties and electrical properties increased first and then decreased with the increase of the amount of PVA.The comprehensive performance of sample P2 was the best,the swelling degree was94.29g/g,the elongation reached3108%,the resistance and conductivity were 7.50 Ω and10.6×10-3 S/m,respectively.关键词
