聚苯乙烯微球自组装胶态晶体的研究及其应用进展∗

摘要

Colloidal crystal has been attracted with considerable interest as a new material,and a common meth-od to prepare colloidal crystal is self-assembly of colloidal particles.Polystyrene (PS)microspheres are common colloidal particles,this paper reviews common methods for self-assembly of PS microspheres to prepare colloi-dal crystal,including vertical deposition,gravitational deposition,interfacial self-assembling,spinning coating and physical limitation,etc.Also,progress of preparation of nanostructure materials with PS colloidal crystal as template or mask is summarized.%胶态晶体作为一种新型材料被广泛关注，一般采用胶态粒子自组装的方法制备胶态晶体。聚苯乙烯(PS)微球是一种常见的胶态粒子，综述了 PS 微球自组装形成胶态晶体的常用方法，包括垂直沉积法、重力场沉积法、界面自组装法、旋涂法及物理限制法等，并对PS胶态晶体用作模板或掩膜制备纳米结构材料的进展进行了总结。
