| 摘要 |
Electrically conductive composite material comprises: (a) an open-celled cellular structure of polymeric material, preferably an open-celled foam, having electrically conductive material on at least its interior surface defining the cells, e.g. deposited metal; and (b) substantially solid, preferably non-conductive, material overlying and/or filling the cellular structure. The solid material (b) is preferably polymeric and may be formed in situ by polymerization of a monomer oligomer or may be introduced e.g. in molten form. The material is useful for electromagnetic shielding, e.g. for cable feedthrough glands or dimensionally recoverable articles.
