"Self-healing" is defined as the ability of a material to recover damages autonomously without any external stimuli. We invented a process to prepare novel polymers and polymer nanocomposites exhibiting self-healing characteristics at room temperature and/or at mildly elevated temperatures. Self-healing polymer nanocomposites were synthesized for the first time and these materials can heal their scratches and cracks by themselves. Our patented technology represents a commercially feasible process for producing a novel class of self-healing materials. Rapid self-healing ability of these polymer nanocomposites is visually demonstrated below
