A method of fabricating optical energy collection and conversion devices using carbon nanotubes (CNTs), and a method of anchoring CNT's into thin polymeric layers is disclosed. The basic method comprises an initial act of surrounding a plurality of substantially aligned nanostructures within at least one fluid layer of substantially uniform thickness such that a first end of the plurality of nanostructures protrudes from the fluid layer. Next, the fluid layer is altered to form an anchoring layer, thereby fastening the nanostructures within the primary anchoring layer with the first ends of the nanostructures protruding from a first surface of the primary anchoring layer. Finally, a portion of the anchoring layer is selectively removed such that a second end of the nanostructures is exposed and protrudes from the anchoring layer. The resulting product is an optically absorbent composite material having aligned nanostructures protruding from both sides of an anchoring layer.

A process and a mold for molding parts. The mold is fabricated using a mixture of a viscous resin such as a gel coat containing nano particles. Electrical conductors are incorporated in the mold surface. The resulting mold in use is heatable by application of electricity to produce parts substantially reducing cure and post cure time. Completed parts containing conductive nano particles may also be produced and are heatable in use for applications where it is desirable to heat the part in use such as de-icing panels. A composition for fabricating parts containing a resin and nano particle segments in sufficient quantity to establish a conductive path is also disclosed.
