Abstract
Self-healable silicone materials have great technical impacts in coatings, smart actuators and flexible electronics, however, current self-healable silicone materials are lack of mechanical tunability. Here, we designed and synthesized a new type of self-healable silicones through hydrogen-bond assisted multiphase assembly of siloxane oligomers. Besides the enhanced mechanical strength, unique water-enhanced healing was observed in the polymer network which is due to the fast and reversible dissociation/association of multivalent hydrogen bonds in the presence of water.
