摘　　要：准聚轮烷以其独特的艺术美学拓扑结构和优异性能,引起了材料学家极大的研究兴趣。该文对基于准聚轮烷制备具有光响应性薄膜的实验进行了探索。首先利用柱[5]芳烃和聚亚甲基的主客体络合,构建了偶氮苯衍生化柱[5]芳烃(P5-Azo)和聚亚甲基嵌段聚苯乙烯(PM-b-PS)的准聚轮烷;然后采用呼吸图法,通过制膜条件的优化,分别在水汽氛围和乙醇氛围下制备出准聚轮烷多孔薄膜和微球薄膜;最后研究了准聚轮烷薄膜紫外光照射前后润湿性的变化。Polypseudorotaxanes have aroused great research interest among materials scientists due to their unique artistic aesthetic topologies and excellent properties.In this paper,experiments on the preparation of polypseudorotaxane-based films with photo-responsiveness were explored.First,a novel polypseudorotaxane was constructed from azobenzene-derivatized pillar[5]arene(P5-Azo)and polymethylene-b-polystyrene(PM-b-PS)based on the host-guest interaction of P5 and PM.Then,after optimizing the preparation conditions,polypseudorotaxane-based porous films and microsphere films were obtained in water vapor atmosphere and ethanol atmosphere via breath figure method,respectively.Finally,the wettability changes of polypseudorotaxanebased films were investigated before and after UV irradiation.
