Rezumat:

Microcellular carbon (CMC) is a distinct material obtained by the polymer matrix pyrolysis containing hard fusible and inert micronized materials by comparison with carbon foam where usual the pyrolized polymers are foamed with different agents. The microcellular carbon is an advanced material due to its properties related to inertness and thermal conductivity where high rate of heat exchange is required and its application to gas separation due to chemical properties from functional groups and controlled pore sizes. This contribution deals with the structural and morphological investigation for CMC resulted from polyacrylonitrile blended with various grain size salts. The pyrolysis and the thermal treatment of the composite has been performed up to 700 0C.
