通过无皂乳液聚合的方法制备出单分散的聚苯乙烯（PS ）微球，采用垂直沉降法降之自组装成具有光子带隙的蛋白石结构。采用SEM 、IR等测试方法对PS光子晶体的表面形貌、结构及光学特性进行测试。讨论了苯乙烯（st）、甲基丙烯酸（MAA）、过硫酸钾（K2S4O8，Kps）的加入量对PS粒径和结构色的影响。结果表明：随着st或Kps含量的增加，PS的粒径随之增加；随着M A A加入量的增加，PS的粒径随之减小。研究发现，光子禁带随粒径的增加逐渐红移。

Mono‐disperse polystyrene spheres were synthesized by soap‐free emulsion poly‐merization ,and their highly ordered colloidal crystals were prepared by vertical surface method .Scanning Electron Microscope (SEM )、Infrared Ray (IR ) ,X‐Ray Diffractometer (XRD) etc were used to study the topography ,structure and optical properties of the PS col‐loidal crystals .The influences of the amount of styrene(st) ,methacrylic acid(MAA) and po‐tassium persulfate(K2 S4 O8 ,Kps) to the size of PS spheres and structural color were studied respectively .The results are that with the increase of the amount of st or Kps ,the size of PS spheres is increasing ;while when the amount of MAA is added ,the particle size is decrea‐sing .The redshift of photonic band gap is caused with increasing particle size .
