Hydrogels based on conducting polymers possess vast applications in the area of flexible electronics including strain sensors and energy storage devices. A lot of traditional synthetic routes to robust conducting polymer hydrogels always rely on an in-situ polymerization of the monomers or a processible conducting polymer dispersion, which is neither controllable nor cost-effective. The present work provides a facile method to obtain high-quality conducting hydrogels based on as-synthesized polypyrrole (PPy) nanotubes through solution infiltration followed by construction of a dual cross-linking network. In this way, both the properties of PPy nanotubes and the cross-linking manner of the hydrogel matrix polymers can be finely adjusted, which provides useful reference for the developing of high-performance flexible electronic materials.
