Abstract: Carbon foams were prepared from diphenolic acid-based benzoxazine foams by pyrolysis under nitrogen atmosphere. The method used in this article produced foams containing a large fraction of closed cells which is uncommon for carbon foams. The foams studied were found to possess similar mechanical properties common to other carbon foams; however, the presence of the high fraction of closed cells led to the lowest observed thermal conductivity ever reported for this class of foams.
