More Information
Summary:A curable liquid carbon precursor formulation for preparing a porous carbon composition including (a) at least one aromatic epoxy resin; (b)(i) at least one aromatic co-reactive curing agent, or (b)(ii) at least one catalytic curing agent, or (b)(iii) a mixture thereof; and (c) at least one porogen; wherein the liquid composition has a neat viscosity of less than 10,000 mPa-s, at 25 DEG C prior to adding porogen, prior to adding optional components, prior to curing, and prior to carbonizing; and wherein the liquid composition being cured has a carbon yield of at least 35 weight percent disregarding the weight of the porogen and any optional components present in the composition; a process for preparing the porous carbon composition from the above formulation including the steps of curing the formulation, and carbonizing the cured product resulting from curing the formulation such that a porous carbon composition is produced; and a porous carbon composition made by the above process.
