  • Material with directional thermal conduction and thermal insulation and preparation method thereof
    Patent number: 11794383
    Abstract: Disclosed is a material with directional thermal conduction and thermal insulation and a preparation method thereof. The method includes: (1) dispersing a viscose-based carbon fiber in water and adding a phenolic resin and polyacrylamide sequentially to obtain a dispersion I; dispersing a high-thermal conduction carbon fiber in water and adding a phenolic resin and polyacrylamide sequentially to obtain a dispersion II; (2) dividing equally the dispersion I and the dispersion II into several parts, respectively, pouring each part of the dispersion I and each part of the dispersion II into a mold alternately until all the dispersion I and the dispersion II are poured, draining after each pouring of a part of the dispersion I or a part of the dispersion II to obtain a porous carbon fiber skeleton, and solidifying the skeleton to obtain a preform; (3) subjecting the preform to a heat treatment to obtain the material.
