Abstract

See full text

A process for the manufacture of a reflective conductive film comprising: (i) a reflective polymeric substrate comprising a polymeric base layer and a polymeric binding layer, wherein the polymeric material of the base layer has a softening temperature TS-B, and the polymeric material of the binding layer has a softening temperature TS-HS; and (ii) a conductive layer comprising a plurality of nanowires, wherein said nanowires are bound by the polymeric matrix of the binding layer such that the nanowires are dispersed at least partially in the polymeric matrix of the binding layer, said process comprising the steps of providing a reflective polymeric substrate comprising a polymeric base layer and a polymeric binding layer; disposing said nanowires on the exposed surface of the binding layer; and heating the composite film to a temperature T1 wherein T1 is equal to or greater than TS−HS, and T1 is at least about 5° C. below TS-B.
