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 anti-icing properties of the coatings, composite coatings were developed by introducing phase-change microcapsules (PCMs). Room temperature vulcanized silicone rubber and a fluorosilicone methacrylate copolymer were examined. Tests involving infrared thermal imaging, icing delay time, and ice shear strength were performed to determine the anti-icing properties of the coatings. It was found that during cooling the composite coatings containing PCMs could release the latent heat of phase change to delay the icing process of water droplets on its surface. The introduction of PCMs increased the surface roughness, and the ice shear strengths of the composite coatings could remain at a low level and ice on the coatings could be easily removed, indicating that PCMs could be practicably applied in anti-icing coatings.

The coatings were cooled from 208C to 2208C at a cooling rate of 108C/min and the time of 0s indicated the time when the temperature was decreased to 08C.

Microencapsulation of binary mixture of 75% stearic acid (SA) + 25% capric acid (CA) (as core) has been amalgamated by silica (as shell) through sol-gel method. The obtained silica binary mixture (Si-BM) microcapsules was characterized in detail by sophisticated instruments such as field emission scanning electron microscope (FESEM), Fourier transformation infrared spectroscopy (FTIR), X-ray diffractometer (XRD), differential scanning calorimeter (DSC), and thermogravimetric (TG/DTA) were exploited to identify shape and mean size, functional groups, nature of crystallinity, and weight loss of Si-BM. The obtained microcapsules were regular in shape, crystalline state, mean size about 6.03 μm and the encapsulation efficiency of Si-BM found to be 71%. The dissimilar microcapsules such as Si-BM and melamine formaldehyde phase change material (MF-PCM) were assimilated (1, 3, and 5 wt%) into cement paste to elucidate thermal-mechanical properties. As the amount of Si-BM increases, the compressive strength increased by 10% and thermal conductivity of cement paste is increased by 9% as compared to MF-PCM. Novelty StatementEncapsulation of binary mixture is synthesized with silica through chemical method. The nonidentical different dosage of microcapsules such as MF-PCM and Si-BM were incorporated into pure cement system to determine its effect on mechanical and thermal properties of cementitious system. These data will be useful to further incorporation in mortar and concrete for energy storage as well as thermal load reduction on buildings.
