摘要
聚合物转化陶瓷(polymer derived ceramics,PDCs)制备技术简单,烧结温度低,可设计性强,40年来得到了极大的发展。本文综述了多孔PDCs的研究进展,包括模板法、发泡法、冷冻铸造技术、增材制造技术等制备方法;此外,还对陶瓷前驱体如聚碳硅烷、聚硅氧烷、聚硅氮烷等分子侧链设计以调整陶瓷产物的组成、微结构、力学性能等的研究现状进行了综述;提出未来发展的方向是增材制造技术制备多孔 PDCs及陶瓷前驱体分子层面的设计。
Polymer derived ceramics (PDCs) has been greatly developed over the past 40 years, due to its advantages of simple operation, low sintering temperature and strong design ability. The research progress of porous PDCs, including template method, foaming method, freeze casting technology, additive manufacturing technology and other preparation methods is reviewed in this paper. In addition, the molecular side chain design and synthesis of ceramic precursors such as polycarbosilane, polysiloxane and polysiloxane for adjusting the composition, microstructures and mechanical properties of porous PDCs are summarized. It is proposed that the design of ceramic precursors and the additive manufacturing method may be the future development direction in porous PDCs.
