羧基化聚苯乙烯微球的快速自组装

Rapid Self-assembly of Carboxyl Polystyrene Microsphere

使用无皂乳液聚合制备出单分散羧基化聚苯乙烯微球,并自组装成胶体晶体阵列.采用FT-IR,DLS和Zeta电位分析对所用羧基化微球进行了表征;通过扫描电子显微镜观察了制得的胶体光子晶体表面形貌.实验结果和根据布拉格方程计算所得数据基本一致,证明该方法既可行又可靠.

Monodisperse carboxyl polystyrene particles prepared by soap-free emulsion copolymerization could be spontaneously self-assembled into crystalline colloidal arrays.The microspheres had been fully characterized by using FT-IR,DLS and Zeta potential analysis,respectively.The scanning electron microscopy was used to observe the surface of colloidal photonic crystals.Their transmission spectra exhibit clearly the energy gaps,which are in agreement with the simulation results according to Bragg＇s law.
