摘要
采用溶胶凝胶法制备了多种不同粒径的单分散二氧化硅胶体微球,并利用制备的微球以垂直沉积自组装法在瓷胎表面制备了颜色艳丽的结构色釉.研究了微球粒径的工艺控制方法及微球尺寸对结构色的影响.SEM分析表明:在二氧化硅微球制备过程中,随着反应液中氨水和正硅酸乙酯浓度的增大,微球粒径逐渐增大;水解、缩聚反应温度升高,微球尺寸会逐渐减小;体系水浓度增大,二氧化硅微球尺寸先增大后减小,存在一个峰值.薄膜分析表明,具有良好三维有序密堆积结构的薄膜,其颜色随着自组装用微球粒径的增大发生红移,色调发生变化,从而能够生成多种结构色釉.
Structural color glazes were assembled by a variety of different size of monodisperse silica colloidal microspheres prepared by sol-gel on porcelain body with vertical deposition method.The influences of particle size on structural color and the control methods of particle size were researched.SEM analysis shows that the size of the silica microspheres become large as increasing amount of ammonia and TEOS in the preparation process,but will decreases as the increase of reaction temperature.The size of the microspheres will increase to the maximum and then decrease with the rise of water concentration.And it is found that the films with good three-dimensional orderly close packing structure could have red-shift of the color by increasing the particle size,by this way,we have made various structural colors glaze.
