摘要：

制备了由单分散聚苯乙烯微球构成的结晶化胶体阵列结构, 并制备了结晶化胶体阵列聚丙烯酰胺水凝胶薄膜. 通过微区反射光谱研究了其光子带隙位置随外加压力的变化规律. 实验结果表明, 该薄膜在垂直表面方向存在光子带隙, 并在一定载荷范围内带隙波长随外加压力呈可逆线性变化.

Abstract:

Polymer-immobilized crystalline colloidal array(PCCA) films composed of polyacrylamide were fabricated by photoinitiated polymerization based on crystalline colloidal arrays composed of monodisperse polystyrene(PS) particles. The stress-sensitive optical property of PCCA film was investigated by micro-region reflectivity spectrometer under a series of loads. It was revealed that an acute peak can be found in the reflectivity spectrum of PCCA film, which was corresponding to the photonic bandgap of the film, and the midgap wavelength shifted approximately linearly and reversibly with load.
