Summary:Production of carbon foam comprises (a) treating a carbonizable polymer with a blowing agent, (b) foaming the mixture and (c) pyrolyzing the mixture. Production of carbon foam comprises (a) treating a carbonizable polymer with a blowing agent, (b) foaming the mixture and (c) pyrolyzing the mixture. Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Kohlenstoffschaums. Um Endprodukte mit hoher chemischer Beständigkeit und niedriger Dichte herzustellen, wird ein Verfahren, umfassend die folgenden Verfahrensschritte vorgeschlagen: DOLLAR A - Versetzen eines carbonisierbaren Ausgangspolymers mit einem Treibmittel, DOLLAR A - Aufschäumen so gewonnener Mischung und DOLLAR A - anschließendes Pyrolysieren der Mischung.
