Abstract

The effects of pre-oxidation for naphthalene mesophase pitch on the surface chemical properties, component distribution as well as the foaming conditions, pore structures and microstructures of carbon foam were investigated. After the given mesophase pitch is oxidized at 210℃ for 2h in air, the composition of quinoline insoluble increases by 32.3% and the component distribution tends to narrower. The average pore size and compressive strength of the resultant graphitized foam are about 200μm and 2.8MPa, respectively, under the foaming condition of 600℃/3MPa.

Key words： carbon foam; mesophase pitches; pre-oxidation
