中文摘要：

应用重力沉降法将粒径单分散的聚苯乙烯微球在蚕丝织物上进行自组装获得光子晶体结构。应用场发射扫描电子显微镜（FEsEM）分析表征了自组装后蚕丝织物表面光子晶体结构的形貌，以及织物与光子晶体契合的界面状况，进而推知纳米微球在蚕丝织物上的组装过程。结果表明，纳米微球在蚕丝织物上自组装得到的光子晶体为三维面心立方结构；自组装过程首先发生在纤维与纤维间隙，进而发生在纤维表面，最终形成长程有序的光子晶体结构；光滑平整的纤维／织物表面有利于纳米微球的自组装和光子晶体结构的构建。

英文摘要：

Polystyrene microspheres with monodisperse particles are self-assembled on silk fabric with gravitational sedimentation method, thus photonic crystal structure is obtained. FESEM analysis is used to characterize the feature of photonic crystal structure on the surface of silk fabric after self-assembly and the interface state of matching of fabric and photonic crystal. Then, the assembly process of nanoparticle on silk fabric is inferred. The result shows that photonic crystal obtained by self-assembly of nanoparticle on silk fabric has three-dimensional surface and centered cubic structure. Self-assembly process first occurs in the gap between fibers, then on the fiber surface. Finally, a long-range and orderly photonic crystal structure forms. Smooth fiber/fabric surface is conducive to self-assembly of nanoparticle and establishment of photonic crystal structure.
