Abstract:

An active barrier to termites and other insects includes a polymeric or paper substrate; and a copper-carbon matrix, wherein the copper-carbon matrix is incorporated into or is coated onto the polymeric or paper substrate. The resulting combination of the substrate and copper-carbon matrix allows for the creation of films, tapes, coated paper and fabric, or molded or formed parts that interfere with and block the passage or entry beyond the barrier of termites or other insects. Uses may be as diverse as but not limited to underlayment(s) for temporary, semi-permanent or permanent structures as well as films and barriers for walls, roofs of permanent, semi-permanent or temporary structures, or interior spaces, cabinets, or vehicles or protecting equipment, telecommunication gear, electronics or other assets that may be impacted, damaged or degraded by termite or other such insect infestation.
