Monolithic open macroporous carbons of 80-85 % porosity are obtained from pyrolyzing oxidized high internal phase templated poly(dicyclopentadiene) foams. The macropores void diameters of the resulting carbon foams can be ajusted between 87 and 2.5 mikrometer simply by changing the surfactant amount used in the preparation of the precursor foams. The resulting porous carbon materials are charcterized by a carbon content >97%, an electronic conductivity of up to 2800 S/m, a Young's modulus of up to 2.1 GPa and a specific surface area of up to 1200 m2/g.
