摘要: 碳黑粒子(CSPS)具有纳米级的尺寸和良好的光热性能，是光热涂层材料的重要候选原料。本文通过不完全燃烧大豆油制得CSPS，以CSPS、碱改性聚偏氟乙烯(MPVDF)和环氧树脂(ER)为主要原料构建CSPS/MPVDF-ER复合涂层，并对影响复合涂层的光热性能、疏水性等各种因素进行了研究。结果发现：CSPS/MPVDF-ER的拒水性能随着CSPS的加入显著提升(水接触角(WCA)>163°，水滚动角(WSA)<1°)。随着CSPS添加量增大，CSPS/MPVDF-ER涂层的光热转化效率逐渐增强，其接触角和抗水流冲击能力呈现出逐步增强的趋势，在CSPS/MPVDF-ER质量比为0.05时涂层达到最大光热转化效果(与环境的温度差ΔT=88℃)。CSPS/MPVDF-ER涂层具有较好的耐受酸、碱及紫外线性能。由来源广泛CSPS通过简单的方法制得的CSPS/MPVDF-ER涂层具有优良的光热转化效果和超疏水性能，为低成本高强度超疏水防污光热涂层的制备提供了一种新的思路。Abstract: Carbon soot particles (CSPS) widely exists and is easy to collect in the production and living, with the size of the nanoscale and good photothermal properties, is one of the important candidate materials for photothermal materials. CSPS are obtained by collecting the incomplete combustion by-products of fuels such as candles and edible oils. The composite coating CSPS/MPVDF-ER was constructed with carbon soot particles, alkali modified polyvinylidene fluoride (MPVDF) and epoxy resin (ER) as the main raw materials, and various factors affecting the photothermal properties, hydrophobicity of the composite coating were studied. The results show that the water repellency of CSPS/MPVDF-ER is significantly improved with the addition of CSPS (Water contact angle (WCA)>163°, water sliding angle (WSA)<1°). With the addition of CSPS, the photothermal efficiency of CSPS/MPVDF-ER coating is gradually increased, and the contact angle and water impact resistance of CSPS/MPVDF-ER coating are gradually enhanced. The maximum photothermal efficiency (temperature difference with the environment ΔT=88℃) of the coating is reached when the mass ratio of CSPS and MPVDF-ER is 0.05, CSPS/MPVDF-ER coating has good resistance to acid, alkali and UV. The CSPS/MPVDF-ER coating prepared by a simple method from a wide range of CSPS nanoparticles has excellent photothermal conversion efficiency and superhydrophobic properties, which provides a feasible method for the preparation of low-cost and high-strength superhydrophobic antifouling photothermal coatings.
