  • Porous article having open pores prepared from aromatic condensation polymer and use thereof
    Patent number: 4753717
    Abstract: An insoluble and infusible substrate with a polyacene-type skelatal structure having a hydrogen/carbon atomic ratio of from 0.05 to 0.60 and containing open pores having an average diameter of not more than 10 micrometers, said substrate being a heat-treated product of an aromatic condensation polymer consisting of carbon, hydrogen and oxygen. The substrate, when doped with a dopant, gives an electrically conductive material. When having a specific surface area of at least 600 m.sup.2 /g, the substrate is especially useful as an electrode of an organic cell.
