Cover Story: Conductive polymer gels have demonstrated great promise for applications in stretchable electronics, biomedical devices and supercapacitors. The inclusion of nanoparticles in conductive polymer gels could improve their mechanical stability and their chemical functionality. In this work, conductive polymer composite gels are prepared via physical mixing of poly(3-hexylthiophene) and ZnO nanowires in a good solvent. The polymer gelation spontaneously occurs upon adding the small amount of nanowires. The coil-like polymer chains reorganize into ordered crystals on the nanowire surfaces, with coil-like polymer chains emanating from the crystal bundles to form 3D interconnected networks. The dynamic sol–gel process is investigated rheologically and the gelation conversion as a function of gelation time reveals the involvement of a first-order rate law. View this paper.
