Abstract
The present invention relates conductive nanostructured copolymer materials, such as thin film. In particular, the nanostructured copolymer material comprises plurality of chains substantially parallel to each other, each conductive chain comprising a plurality of conductive polyacetylene polymer blocks positioned along the chain and a plurality of polar poly(vinyl alcohol) polymer blocks in between the polyacetylene polymer blocks to form a pattern of alternatively repeating polyacetylene polymer blocks and poly(vinyl alcohol) polymer blocks and a ratio of polyacetylene polymer to poly(vinyl alcohol) polymer to provide the nanostructured copolymer material with conductivity of at least 1 S/cm. In some aspects, the invention relates to photoelectric devices comprising a nanostructured copolymer material and capable to convert light to electrical current.
