Most of the carbon foams’ preparation is conducted under either high temperature or high pressure which consumes much energy. Aimed at this problem, we proposed a novel preparation technology which utilized the albumen as the foaming agent under normal temperature and pressure. The carbon foams had a bulk density of between 0.38 and 0.44 g/cm3. Analysis of scanning electron micrographs indicated that the cells had spherical cavity, small transom, and ligament which connected spherical cavity and provided high mechanical properties. The compressive strengths ranged from 0.4 to 2.1MPa and the thermal conductivity stayed still when the content of the meso-carbon micro-beads (MCMB) varied between 0 and 10%. It is one of our method’s features that the content of MCMB has litter effect on the thermal conductivity of the carbon foams. |
