The invention relates to methods for the production of carbon-based molded bodies, especially a method for producing porous carbon-based molded bodies by carbonizing organic polymer materials that are mixed with non-polymeric fillers and then detaching the fillers from the carbonized molded body. In an alternative embodiment, the invention relates to a method for producing porous carbon-based molded bodies by carbonizing organic polymer materials comprising polymeric fillers which are decomposed substantially in full during carbonization. Also disclosed is a method for producing porous carbon-based molded bodies by carbonizing organic polymer materials, the carbon-based molded body being partially oxidized following carbonization so as to create pores. The invention finally relates to porous molded bodies produced according to one of said methods and the use thereof, particularly as cell culture carrier systems and/or culture systems.
L'invention concerne un procédé de fabrication de corps moulés à base de carbone, en particulier, un procédé de fabrication de corps moulés poreux à base de carbone, par carbonisation de matériaux polymères organiques qui sont mélangés avec des charges non polymères, et élimination subséquente, par un solvant, de la charge du corps moulé carbonisé. Suivant une variante, l'invention concerne un procédé de fabrication de corps moulés poreux à base de carbone, par carbonisation de matériaux polymères organiques avec des charges polymères qui sont sensiblement totalement dégradées au cours de la carbonisation. En outre, l'invention concerne un procédé de fabrication de corps moulés poreux à base de carbone, par carbonisation de matériaux polymères organiques, procédé dans lequel le corps moulé à base de carbone est, après carbonisation, partiellement oxydé pour la production de pores. L'invention concerne également des corps moulés poreux, fabriqués suivant le procédé précité, ainsi que leur utilisation, en particulier dans des systèmes de supports de cultures cellulaires et/ou d'implants.
