METHOD OF PREPARATION OF POROUS CARBON MATERIAL AND MATERIAL PRODUCED BY THE METHOD

A porous carbon material is prepared by (a) forming a carbonizable polymer structure having a porous structure of cells and optionally pores interconnecting the cells by condensation polymerization in which polymerization precursors are present in the continuous phase of a high internal phase oil-in...

Beschreibung
Zusammenfassung:	A porous carbon material is prepared by (a) forming a carbonizable polymer structure having a porous structure of cells and optionally pores interconnecting the cells by condensation polymerization in which polymerization precursors are present in the continuous phase of a high internal phase oil-in-water emulsion and (b) carbonizing the carbonizable polymer structure by heating in an inert atmosphere to at least 500 DEG C. The internal (oil) phase of the emulsion may be at least 74% by volume. The material produced has high strength.
