Multiple hydrogen bonding interactions toward rapidly self-healing, photothermal conversion elastomer composites

Despite the photothermal conversion elastomers were widespread used in solar power collection and shape-morphing devices, the fabrication of photothermal conversion elastomer integrated with low cost, fast self-healing, high healing efficiency, and comparable mechanical property, remained a challenge. To address this issue, we reported a kind of elastomer composites with fast self-healing and excellent photothermal conversion property through the multiple hydrogen bonding interactions between natural rubber (NR), carboxylate cellulose nanocrystal (C–CNC) and polydopamine (PDA).
