我们开发了由液晶、微粒和金纳米棒组成的光可修复复合凝胶。在用近红外光照射时，复合凝胶的温度通过金纳米棒的光热效应迅速升高到凝胶-溶胶转变温度以上。在此基础上，利用光热效应诱导液晶相变的原理，成功地实现了复合凝胶的光诱导凝胶-溶胶相变。此外，我们还利用光热凝胶-溶胶转变实现了复合凝胶表面裂纹的光修复。
We developed photo-healable composite gels consisting of liquid crystal, microparticles, and gold nanorods. Upon irradiation with near-infrared light, the temperature of the composite gels rapidly increased above a gel-sol transition temperature by the photothermal effect of gold nanorods. Then, we successfully performed photoinduced gel-sol transition of composite gels based on the phase transition of liquid crystals induced by the photothermal effect. In addition, we achieved photo-healing of surface cracks made on the composite gels by means of the photothermal gel-sol transition.
