A method of forming a carbon foam material comprises forming an emulsion may include a phenol formaldehyde and hexamine in monoethylene glycol and water, curing the emulsion to yield a cured resin, and carbonizing the cured resin to form the carbon foam material. Forming the emulsion may include dispersing the phenol formaldehyde and hexamine in the monoethylene glycol to form an initial solution, contacting the initial solution with the water to form an initial emulsion, and agitating the initial emulsion to form an agitated emulsion. The method may further comprise contacting the agitated emulsion with an oil. Also, a carbon foam material that may be characterized as exhibiting a density of less than about 0.500 g/cc, as exhibiting a compressive strength equal to or greater than about 200 psi, or both.
A carbon foam material characterized as exhibiting a density of less than about 0.500 g/cc, an average pore size from about 3,000 μm to about 7,000 μm a compressive strength from about 200 psi to about 2000 psi, a compressive modulus equal to or greater than about 30 ksi, and a tensile modulus of equal to or greater than about 30 ksi.
