Polymers with low surface energy such as silicone and fluoropolymers are widely applied in preparing anti‐icing coatings, but they may have some limitations. To improve the properties of composite coatings were developed by introducing phase‐change microcapsules (PCMs). Room temperature vulcanized rubber a fluorosilicone methacrylate copolymer examined. Tests involving infrared thermal imaging, icing delay time, ice shear strength performed to determine coatings. It was found that during cooling containing PCMs could release latent heat phase change process water droplets on its surface. The introduction increased roughness, strengths remain at level be easily removed, indicating practicably POLYM. ENG. SCI., 58:973–979, 2018. © 2017 Society Plastics Engineers
