Highly thermally insulating and electrically conductive graphene aerogel and method of manufacturing thereof
Original language description
The present invention relates to a graphene aerogel, a method of manufacturing the same, and a method of increasing the electrical conductivity while decreasing the thermal conductivity thereof. The graphene aerogel according to the present invention is a porous carbon material that is mechanically stable, elastic, and has damping and non-flammable properties. The aerogel comprises two-dimensional carbon materials that are interconnected via covalent and van der Waals bonds to form a three-dimensional porous structure. The electrical conductivity is from 50 to 400 S/m, when the aerogel is compressed. Furthermore, the thermal conductivity of the graphene aerogel is from 10-3 to 10-1 W m-1K-1, when the graphene aerogel is compressed to at least 5% of strain. The method of manufacturing is characterized in that, it comprises the steps of forming three-dimensional structures of the aerogel, wherein the three-dimensional structures comprise covalently cross-linked two-dimensional carbon materials, thereby forming a free-standing aerogel, and compressing of the free-standing aerogel to at least 5% of strain, and fixing the compression of the graphene aerogel.
