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.
