Abstract A flexible composite gel based on multiple hydrogen bonding interaction is prepared by using the P = O ∕ P − O group. And it presents remarkable stretchability and self-healing efficiency (nearly 100%). Mechanical property is investigated by analyzing the stress–strain curves and hydrogen bonding interaction is explored by density functional theory. This study reveals that mechanical property of the polyaniline is improved by establishing dynamic hydrogen bonding with flexible molecular chains.
