US Patent 7919037 - Molding heatable articles with nanoparticles

This patent teaches a fabrication method for molded polymer articles containing carbon nanotubes. Claim 1 reads:

1. A process for molding a part comprising:

(a) providing a mold having a mold surface containing embedded elongate nano particles uniformly distributed throughout the mold and electrical conductors embedded in said mold in spaced-apart relationship extending substantially through the mold surface;

(b) applying a resin to the mold surface;

(c) applying electrical energy to said conductors to cause said mold surface to be heated by electrical energy flowing between said conductors via said nano particle to accelerate curing of the resin forming the part; and

(d) de-molding the part.
