采用分子动力学方法对偏钒酸铯(CsVO3)与3种聚合物的表面吸附能进行了模拟计算.根据计算结果,选择苯乙烯-甲基丙烯酸甲酯共聚物(P(SGMMA))作为包覆层,采用超声偶联-原位分散聚合法制备了CsVO3/P(SGMMA)复合荧光微球,进而旋涂成膜,并对其结构与性能进行表征. 结果表明,CsGVO3/P(SGMMA)复合材料尽管发光强度有所减弱,但其避免了CsVO3 粉体的团聚,扩展了CsVO3 在柔性发光与显示器件中的应用.
The interaction manners between three polymers and CsVO 3 crystal surfaces were simulated.On the basis of theoretical calculation CsVO 3/P(S-MMA)powder was prepared by ultrasonic-coupling and in-situ dis-persion polymerization.And its film was obtained by spin coating.Their structure and properties were charac-terized.Results show that direct fabrication of the CsVO 3/P(S-MMA)would be advantageous not only to avoid particle aggregation but also to further expand potential applications for flexible devices.
