Low-Density Microcellular Carbonized Polyacrylonitrile (PAN) Foams

摘要

Carbon foams are of interest for numerous applications including: porous electrodes, filters, high temperature insulation, catalyst supports, and as structural materials for the fabrication of inertial confinement fusion targets. Carbon foams have improved thermal and chemical stability when compared to polymer foams and provide improved dimensional stability. We have reported a new process for preparing carbon foams which involves the preparation of low-density PAN foams which can be carbonized. The unique properties of these materials and several developing applications for carbonized PAN foams are described. 3 refs., 6 figs., 2 tabs. (ERA citation 13:057049)
