Anisotropically shaped composite particles were prepared in wet chemical processes for creating new types of colloidal crystals. The preparation of anisotropic composite particles were performed by incorporating inorganic components into polymers that are main components of composite particles. The inorganic components incorporated were used as materials responsive to external fields such as electric and magnetic fields. Localization of the inorganic components in the composite particles could assemble the composite particles with their directed orientation. Hollow particles incorporating a movable core could be a new type of building block to create non-close packed colloidal crystals responsive to external fields.

采用湿化学工艺制备形状各向异性的复合颗粒，用于制造新型胶体晶体。 各向异性复合颗粒的制备是通过将无机组分掺入作为复合颗粒主要成分的聚合物中来进行的。 所掺入的无机成分被用作对电场和磁场等外部场敏感的材料。 复合颗粒中无机组分的定位可以以其定向组装复合颗粒。 包含可移动核心的中空颗粒可能是一种新型的构建块，用于创建响应外部场的非密堆积胶体晶体。
