Disclosed herein are self-healing conductive network compositions. The networks can contain one or more conductive polymers and one or more supramolecular complexes. The supramolecular complex can be introduced into conductive polymer matrix, resulting in a network of the two components. In this network, the nanostructured conductive polymer gel constructs a 3D network to promote the transport of electrons and mechanically reinforce the network while the supramolecular complex contributes to self-healing property and also conductivity. The networks disclosed herein are useful for various applications such as self-healing electronics, artificial skins, soft robotics and biomimetic prostheses.
