文摘

Polymer composites with metal nanoparticles have attracted considerable attention over the past years due to numerous solid state potential applications in organic electronics and microelectronic devices. Here we report the first example of a novel, rapid and convenient self-directed dual surface nano-silvering of a polymer film by a simple single-stage process of free-radical photopolymerisation (UV-curing). The major component of the composite is bisphenol A ethoxylate dimethacrylate (BEMA) which can be photopolymerised by a photo-reactive initiator (Darocur 1173) under UV light. Under the same conditions of UV irradiation, silver nitrate decomposes and the silver ion is deposited as metal while the pyrrole is oxidised to polypyrrole. It is demonstrated that this versatile method can open up promising prospective in obtaining innovative composite polymeric capacitors for highly flexible and/or non-planar electronics application. The obtained films are characterised by Scanning Electron Microscopy (SEM) and electrical measurements.
