摘　　要：综述了利用共连续亚微观结构和填料的选择性分散来设计和制备功能与智能高分子材料的最新研究成果。重点介绍了双连续结构的形成及其在介电绝缘材料、导电导热材料和形状记忆材料等体系中的应用。与"海-岛"结构相比,"双连续"结构中的两个组分都可以形成三维网络结构,因而都可看作基体相,有利于材料的力学、导电以及导热等性能的协同提高。通过控制功能性金属或无机填料在共连续结构中的选择性分散可以在很大范围内调节和优化材料的功能和智能特性,为设计和制备新型高分子纳米复合材料提供了新思路。The latest progress in the design and preparation of functional and smart polymer materials with fillers＇ selective localization in cocontinuous submicroscopic architecture was reviewed. The forma- tion of bicontinuous structure and its applications in the dielectric and insulating materials, electrically and thermally conductive materials, and shape memory materials were introduced mainly. Compared with the ＂sea-island＂ architecture where one phase is the continuous phase while the other phase is the dis- persed phase, the two phases of cocontinuous architecture can form three-dimensional network and can be taken as continuous matrices. Such a structure is benifical to synergistic improve .the mechanical, electrically conductive, and thermally conductive properties of materials. Besides, by controlling the selective localization of functional metallic or inorganic fillers in the cocontinuous architecture, the functional and smart characteristics of materials can be tuned and optimized in a wide range. This strategy provides a new idea on the design and preparation of novel polymer nanocomposite materials.
