Abstract
An electrically conductive polymer linked to conductive nanoparticle is provided. The conductive polymer can include conductive monomers and one or more monomers in the conductive polymer can be linked to a conductive nanoparticle and can include a polymerizable moiety so that it can be incorporated into a polymer chain. The electrically conductive monomer can include a 3,4-ethylenedioxythiophene as a conductive monomer. The electrically conductive polymer having the conductive nanoparticle can be prepared into an electrically conductive layer or film for use in electronic devices.
