摘要/Abstract

摘要： 两种经过化学修饰的PPV(聚对苯撑乙烯)类共轭高分子共聚物分别与纳米TiO₂复合,作为有机/无机复合材料进行研究.这两种共聚物在乙醇、二氯甲烷溶液中分别与以Sol-Gel法、反胶束法制得的TiO₂共混得到均匀分散的体系而不出现相分离.用共聚物与TiO₂的复合液可以在石英基底上制成均匀的复合膜.结果表明,高聚物/TiO₂复合物的光物理特性与单纯的高聚物相比呈现明显的差异;不同粒径的纳米TiO₂对复合物性能的影响不同;中间苯环的取代基对共聚物的性质影响明显.共轭高分子与纳米TiO₂复合涂膜后其发光性能明显改善,有作为发光器件的应用前景.

Abstract: Two kinds of organic/inorganic composites containing poly(phenylenevinylene)(PPV)derivative polymer and nanosized TiO₂ were intensively investigated.Both the two polymers can be stably mixed with nanosized TiO₂ particles obtained by using either Sol-Gel method or reversed micelle method in organic solvent such as ethanol and methylene chloride.By coating such solution on silica substrate,transparent composite films were made.The photophysical properties of polymer/TiO₂ composites are evidently different from the pure polymers.The study shows the methoxy groups on the middle benzene ring change the polymer’s characteristics distinctly.The substituents and the size of TiO₂ particles affect on the photophysical properties of polymers.The polymers’ luminescence properties have been apparently improved as they formed organic/inorganic composites with TiO₂ particles.

Key words: poly(phenylenevinylene) derivative polymer, nanosized TiO₂, organic/inorganic composite
