| description | The invention provides a preparation method of a polymer porous material, which is based on the characteristics that an active pre-crosslinked emulsion not only has a ready-made polymer network and is highly oriented and extended under the extrusion of ice crystals, but also has an unreacted part so as to react at low temperature to fix a highly oriented and extended pore wall structure. The polymer porous material with high porosity (the highest porosity can reach 99.0%, and the density is as low as 0.013 g/cm < 3 >) is obtained by combining the advantages of an ice template method. Due to high porosity, compared with a polymer porous material prepared by a traditional method, the polymer porous material has lower thermal conductivity (the lowest thermal conductivity reaches 18.7 mW/m.K) and better thermal insulation performance, and can be used as a high-performance thermal insulation/sound insulation/shock absorption material.
