The porous polydicyclopentadiene(PDCPD)-based materials which inherit the high modulus of PDCPD have been greatly concerned in recent years. The major methods to prepare porous PDCPD-based materials include sol-gel & supercritical fluid drying,high internal phase emulsion, chemically induced phase separation and chemical foaming. The structure of porous PDCPD-based materials made by different methods determines their various applications. For example, the porous PDCPD-based materials with low-porosity and closed-cell structure that prepared by chemically induced phase separation and chemical foaming can be used as the structural materials. The PDCPD-based composite membrane fabricated by high internal phase emulsion is applied to catalytic reaction. The open-cell PDCPD aerogels made by sol-gel & supercritical fluid drying have high-porosity and low thermal conductivity (<20 mW/(m·K)), which is a good candidate for the thermal insulation materials. The development of the porous PDCPD-based materials are also prospected.
