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.
