ABSTRACT:
The present invention provides a discontinuous metal/polymer composite, with a metal layer, formed from a plurality of fine metal strands, which may be used, for example, in static or EMI shielding. The metal layer comprises a plurality of fine metal strands provided on the substrate, the metal strands individually having a cross-section with an area of about 100 to 100,000 .mu.m.sup.2 and the cross-section of the individual metal strands having a flat portion and an arcuate portion. The metal and polymer may be selected so that the composite is capable of being thermoformed without loss of electrical conductivity or transparency.
