A method of manufacturing to increase the thermal and electrical
conductivity of polymers includes layering a filled polymer with an
unfilled polymer to produce a multi-layered system of alternating filled
and unfilled polymer layers. The filler material comprises thermally
and/or electrically conductive material. A preferred polymer is a shape
memory polymer. A method of manufacturing magnetic multi-layered polymer
systems is described. Articles formed from such multi-layered systems are
also disclosed.
