Composite hydrogel material with self-adaptive solar response as well as preparation method and application of composite hydrogel material
The invention provides a composite hydrogel material self-adaptive to solar response and a preparation method and application thereof.The composite hydrogel material comprises a photo-thermal material and a thermal response phase change material, and the photo-thermal material is a nano composite material formed by compounding a metal-based nano material with a two-dimensional layered nano material; the thermal response phase change material is hydrogel formed by copolymerizing a thermochromic material and a high polymer material containing hydroxyl and carboxyl; the high polymer material containing hydroxyl and carboxyl can provide hydrogen bonds, so that the heat storage capacity is improved, and meanwhile, the solar energy modulation capability of the composite hydrogel is favorably improved. According to the invention, a small amount of nano composite material is used as a light capture nano heater to generate a synergistically enhanced photothermal effect and stimulate the thermal response of the hydrogel; when the composite hydrogel material is applied to an intelligent window or a wearable material, the composite hydrogel material has excellent light absorption performance, photothermal conversion performance and high solar energy modulation amplitude, has a temperature adjusting effect in the aspect of self-adaptive solar energy modulation, and has important significance in energy conservation.
