首先制备氟化超支化聚氨酯(FHPU)，然后与具有光热转化功能的普鲁士蓝(PB)纳米粒子复合，得到光热转换功能的PB/FHPU超疏水防结冰复合涂层材料。利用FTIR、TGA和DSC等测试分析了FHPU和PB/FHPU超疏水防结冰复合涂层材料的结构及性能，通过光热转换实验证明了复合涂层材料出色的光热性能；深入探究了PB纳米粒子的添加量对复合涂层材料表面性质和光热转化性能的影响。结果表明，当PB质量占FHPU的13%时，复合涂层材料可形成具有微纳结构的复合涂层，涂层表面最大接触角达157°，滚动角为1.8°。同时，该涂层在808 nm激光照射下10 s内温度可升高78.1℃，最高温度达到148.7℃。因而，光热转换功能性超疏水防结冰复合涂层材料具有良好的疏水、防结冰性能。 

Prussian blue/fluorinated hyperbranched polyurethane composite coating material and its photothermal conversion superhydrophobic properties

Fluorinated hyperbranched polyurethane (FHPU) was first prepared, and then combined with Prussian blue (PB) nanoparticles with photothermal conversion function to obtain PB/FHPU superhydrophobic anti-icing composite with photothermal conversion function coating material. The structure and performance of FHPU and PB/FHPU superhydrophobic anti-icing composite coating materials were analyzed by FTIR, TGA and DSC tests, and the excellent photothermal performance of the composite coating materials was proved through the photothermal conversion experiment; The effect of the amount of PB nanoparticles added on the surface properties and photothermal conversion performance of composite coating materials was deeply explored. The results show that when the PB mass accounts for 13% of the FHPU, the composite coating material can form a composite coating with a micro-nano structure. The maximum contact angle of the coating surface is 157° and the rolling angle is 1.8°. At the same time, the temperature of the coating can rise by 78.1°C within 10 s under 808 nm laser irradiation, and the maximum temperature reaches to 148.7°C. Therefore, the light-to-heat conversion functional superhydrophobic anti-icing composite coating material has good hydrophobic and anti-icing properties.
