中文摘要：
基于单分散胶体粒子悬浊液在温敏水凝胶表面可以形成湿润型胶体晶体的现象，利用温敏水凝胶对水的控释作用制备了温度敏感的可调制胶体晶体．在室温下利用提拉法在温敏水凝胶聚N-异丙基丙烯酰胺（PNIPAAm）表面制备湿润型胶体晶体膜．由于胶体粒子的有序排列，胶体晶体显示出一个尖锐的反射峰．当温度上升到34℃以上时，由于PNIPAAm水凝胶中的水被释放，导致胶体晶体中粒子浓度降低，粒子间距增加；反射峰发生红移．这些特性可以通过温度变化进行调制．
英文摘要：
Wet type colloidal crystals were fabricated on the temperature-sensitive hydrogel PNIPAAm by dipcoating method. Optical properties of the colloidal crystals were controlled by taking advantage of the water-releasing effect of PNIPAAm. It is found that monodisperse spheres could form ordered three-dimensional structure on the surface of PNIPAAm by lifting hydrogel-coated substrate from latex suspension. The colloidal crystal on hydrogel exhibited a sharp reflection peak originating from the diffraction of light. By raising the temperature over 34℃, phase transition occurred for PNIPAAm. Accompanying with the phase transition, water in PNIPAAm was released to the colloidal crystal, which diluted the concentration of the spheres and increased the interparticle distance. As a result, the reflection peak shifted to the long wavelength side. Such a change can be recovered by decreasing the temperature.
