摘要：
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. © 2024 Beijing University of Aeronautics and Astronautics (BUAA).
