本文综述了聚合物衍生陶瓷纳米复合材料（PDC-NC）的研究进展。简要介绍了不同种类的陶瓷先驱体聚合物，并介绍了它们向具有可调相组成和微观结构的陶瓷材料的转化。重点讨论了前驱体的化学和结构体系与所得陶瓷纳米复合材料的结构特征和性能之间的密切关系。各种结构和功能特性的含硅陶瓷纳米复合材料，以及不同的制备策略，以实现纳米级的PDC-NC为基础的有序结构的突出，基于选定的陶瓷纳米复合材料系统。此外，还详细介绍了PDC-NC在高温稳定热防护材料、热气体分离膜、多相催化材料、储氢纳米密封材料以及二次离子电池负极材料等方面的应用前景。
The present Review addresses current developments related to polymer-derived ceramic nanocomposites (PDC-NCs). Different classes of preceramic polymers are briefly introduced and their conversion into ceramic materials with adjustable phase compositions and microstructures is presented. Emphasis is set on discussing the intimate relationship between the chemistry and structural architecture of the precursor and the structural features and properties of the resulting ceramic nanocomposites. Various structural and functional properties of silicon-containing ceramic nanocomposites as well as different preparative strategies to achieve nano-scaled PDC-NC-based ordered structures are highlighted, based on selected ceramic nanocomposite systems. Furthermore, prospective applications of the PDC-NCs such as high-temperature stable materials for thermal protection systems, membranes for hot gas separation purposes, materials for heterogeneous catalysis, nano-confinement materials for hydrogen storage applications as well as anode materials for secondary ion batteries are introduced and discussed in detail.
