本发明公开了一种光热相变复合材料及其制备方法和在防冰除冰中的应用，所述复合材料包括光热吸收转化载体和负载在其上的相变储能填充剂。本发明通过在光热吸收转化载体上引入具有热能储存与释放能量的相变储能填充剂，当环境温度低于其相变温度时，相变储能填充剂会发生相转变，向周围释放自身已储存的能量；当环境温度高于其相变温度时，相变储能填充剂则会吸收外界能量并储存起来。基于上述优异性能，相变储能填充剂能够以潜热的形式吸收、储存、释放大量的热量，以保持复合材料自身表面温度的恒定。本发明创造性地将相变储能填充剂与光热吸收转化载体相结合，解决了现有除冰材料无法实现全时段除冰效果的技术难题。

The present invention discloses a photothermal phase change composite material, its preparation method and its application in anti-icing and de-icing, said composite material comprising a photothermal absorption conversion carrier and a phase change energy storage filler loaded thereon. The present invention introduces a phase change energy storage filler with thermal energy storage and release energy on the photo-thermal absorption conversion carrier, and when the ambient temperature is lower than its phase change temperature, the phase change energy storage filler will undergo a phase transition, releasing its own stored energy to the surrounding area; when the ambient temperature is higher than its phase change temperature, the phase change energy storage filler will undergo a phase transition, releasing its own stored energy to the surrounding area. When the ambient temperature is higher than the phase transition temperature, the phase change energy storage filler will absorb the external energy and release the stored energy to the surrounding. When the ambient temperature is higher than the phase change temperature, the phase change energy storage filler will absorb the external energy and store it. Based on the above Based on the above advantages, phase change energy storage fillers can absorb, store and release a large amount of heat in the form of latent heat. and release a large amount of heat in the form of latent heat in order to keep the surface temperature of the composite material constant. surface temperature of the composite material. The present invention creatively combines the phase change energy storage filler with the light and heat absorption conversion carrier. The present invention creatively combines the phase change energy storage filler with the light and heat absorption and transformation carrier, which solves the problem that the existing The present invention creatively combines the phase change energy storage filler with the light and heat absorption conversion carrier, solving the technical problem that the existing de-icing material cannot realize the de-icing effect in full time.
