摘　　要：以乙烯基吡咯烷酮(NVP)、甲基丙烯酸异辛酯(EHMA)和三乙烯基乙二醇二乙烯基醚(DVE-3)等材料制作亲水可溶胀膜。研究DVE-3含量对力学性能、亲水性能和溶胀性能的影响,探索紫外光照射时间对材料力学性能的影响。当DVE-3含量为20%时,该亲水溶胀膜的综合性能最佳:拉伸强度为26.2kPa、断后伸长率为119%、压缩模量为53.7kPa、压缩强度为27.4kPa、接触角为22°、PBS溶液中浸泡120h后溶胀率为322%。紫外光照射时间为20s时,材料拉伸性能最好,此时拉伸强度为25.8kPa,断后伸长率为217.9%。A hydrophilic swelling film was made from vinyl pyrrolidone,isooctyl methacrylate and trivinylethylene glycol divinyl ether(DVE-3).The effect of content of DVE-3 on the mechanical properties,hydrophilic properties and swelling properties was investigated,and the effect of UV irradiation time on the mechanical properties of the material was explored.The overall property of the hydrophilic swelling film with 20% content of DVE-3 was the best,which was characterized with tensile strength of 26.2kPa,elongation after break of 119%,compression modulus of 53.7kPa,compression strength of 27.4kPa,contact angle of 22° and swelling rate of 322% after 120h immersion in PBS solution.When the UV irradiation time was 20s,the tensile property was the best with the tensile strength of 25.8kPa and the elongation after break of 217.9%.
