<p>Electrically conductive composite material comprises:
<UnorderedLists id="ula01" listStyle="none"><ListItem>(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</ListItem><ListItem>(b) substantially solid, preferably non-conductive, material overlying and/or filling the cellular structure.</ListItem></UnorderedLists></p><p>The solid material (b) is preferably polymeric and may be formed <Underline style="single">in</Underline><Underline style="single">situ</Underline> by polymerisation of a monomer oligomer or may be introduced e.g. in molten form.</p><p>The material is useful for electromagnetic shielding, e.g. for cable feedthrough glands or dimensionally recoverable articles. </p> |
