Abstract
This invention relates to the production of a novel, porous, carbon structure. A stabilised porous polymer comprising cavities joined by interconnecting pores is heated in an inert atmosphere to yield a stable, porous, carbon structure having the inherent structure of the original stabilised polymer.
Claims9
A porous carboniferous structure consisting of concave surfaces and having at least 80% voids and comprising cavities joined by interconnecting pores and having a density of less than 0.5 g/cm.sup.3, the carboniferous structure being derived from a porous cross-linked polymer formed by polymerising monomer and cross-linking agent as a continous phase of a high internal phase emulsion having an aqueous discontinuous phase.
A process for the manufacture of a porous carbon structure comprising heating a stabilised, cross-linked, porous polymer in an inert atmosphere to a temperature of at least 500.degree. C., the cross-linked porous polymer being formed by polymerising monomer and cross-linking agent as a continuous phase of a high internal phase emulsion having an aqueous discontinous phase.
