利用简单的方法和较少的胶体乳液,在没有任何特殊设备的情况下制备出了二维和三维的有序阵列。通过控制胶体乳液浓度获得了层数可控的胶体晶体有序阵列。通过使用现有成膜模型模拟沉积行为揭示胶体晶体阵列在生长过程中控制冷凝蒸发过程的机理,对自组装过程中颗粒转移和溶剂蒸发之间的平衡细节进行了详细的讨论。利用阵列横截面的SEM显微照片来观测样品的厚度和均匀性,通过反射光谱来观察样品的光学性质。
Using simple methods and less colloidal emulsion, two-dimensional and three-dimensional ordered arrays were prepared without any special equipment. By controlling the colloidal emulsion concentration controllable colloidal crystal ordered array. The mechanism of controlled condensation and evaporation during the growth of colloidal crystal arrays was revealed by using the existing film-forming model to simulate the deposition behavior. The details of the balance between particle transfer and solvent evaporation in the self-assembly process were discussed in detail. The thickness and uniformity of the sample were observed using SEM micrographs of the array cross section and the optical properties of the sample were observed by reflection spectroscopy.
