由 Si O2 胶体颗粒的三维有序自组装可以得到面心立方三维结构 ,它具有折射率周期性变化的特点。它的制备涉及胶体化学、材料科学等学科的前沿领域。其自组装方法包括胶体颗粒的沉降自组装、胶体颗粒在物体限制下的自组装、胶体颗粒的连续对流自组装和利用胶体颗粒表面电性质的自组装。本文对这些组装方法进行了介绍。
By the three-dimensional ordered self-assembly of colloidal silica particles surface-centered cubic three-dimensional structure, which has a periodic change in refractive index characteristics. Its preparation involves the frontier fields of colloid chemistry, material science and other disciplines. Self-assembly methods include the self-assembly of colloidal particles, the self-assembly of colloidal particles under the constraints of objects, the continuous convection self-assembly of colloidal particles and the self-assembly of the electrical properties of colloidal particles. This article describes these assembly methods.
