Au nanoparticles and poly(3-hexylthiophene) (P3HT) composite films were prepared by electrodeposition of Au nanoparticles using pulse-current electrodeposition followed by the spin coating of P3HT and their enhanced electrochromic coloration was investigated. A relatively uniformed Au nanoparticle was obtained by the

Innovative hybrid nanocomposites based on a nanostructured block copolymer (BCP) matrix whose lamellar nanodomains are selectively loaded with metal nanoparticles, have been prepared. A symmetric poly(styrene-b-methylmethacrylate) (PS-b-PMMA) amorphous BCP showing a lamellar morphology has been employed. Thin films of PS-b-PMMA
