Prabhakaran, P. Singh, N. Gokhale, S. Sharma] A novel process for preparation low density carbon foams from sucrose has been demonstrated. A resin prepared by heating aqueous acidic sucrose solution when heated in an open Teflon mould at 120°C undergoes foaming and then setting in to a solid organic foam. The solid organic foam undergoes carbonization in air by dehydration at 250°C under isothermal condition. Carbon foams thus obtained sintered at temperature in the range 600-1,400°C showed density in the range 115-145mg/cc and electrical conductivity in the range 1.5×10−5 to 0.2ohm−1cm−1, respectively. The carbon foams contain spherical cells of size in the range 450-850μm and the cells are interconnected through circular or oval shape windows of size in the range 80-300μm. The carbon foam samples sintered at 1,400°C showed compressive strength of 0.89MPa. Springer Science+Business Media, LLC, 2007 Prabhakaran K.
