蒸发自组装法制备聚苯乙烯胶体晶体
Preparation of Self-Assembled Polystyrene Sphereic Colloid Crystals by a Solvent Evaporation Method
摘要
Abstract
Sub-micrometer monodispersed polystyrene microspheres were synthesized by the emulsion polymerization technique. The three-dimensional ordered polystyrene colloidal crystals were fabricated on the surface of emulsion through a solvent evaporation method. We have fabricated colloidal crystals with the thickness of more than 450 μm by using this method. It was found that the key factor of preparation of colloidal crystal was the evaporation rate. The capillary force was the main driving force for the regular assembling of the colloidal crystal. With the decrease of solvent, the floating capability of microspheres decreased due to the increase of viscosity and caused the increase of defects.关键词
