Creation of non-close-packed colloidal crystals by assemblies of anisotropically shaped particles under external fields

采用湿化学法制备各向异性形状的复合粒子，以形成新型胶体晶体。各向异性复合粒子的制备是通过将无机组分加入到作为复合粒子的主要成分的聚合物中来进行的。所掺入的无机组分被用作响应电场和磁场等外场的材料。无机组分在复合粒子中的定域化可以使复合粒子具有定向取向。含有可移动核心的中空粒子可能是一种新型的构建块，可以响应外场产生非紧密堆积的胶体晶体。

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.
