Strong mechanical and durable superhydrophobic photothermal MWCNTs/SiO2/PDMS/PVDF composite coating for anti-icing and de-icing

Substrate-Independent Superhydrophobic Coating Capable of Photothermal-Induced Repairability for Multiple Damages Fabricated via Simple Blade Coating

“…To clarify the reason for the wettability variation during the plasma treatment–sunlight irradiation cycle, we detected the surface compositions of the original, plasma treated, and sunlight repaired C/P/P coating via FTIR and XPS analyses. As shown in Figure b and c, the original coating exhibits obvious features of asymmetric, symmetric and shake vibrations of −CH 2 group at 2910, 2855, and 720 cm –1 , the stretch vibrations of C–F and C–C groups and Si–C at 1405, 1165, and 837 cm –1 , and the shake vibration of Si-CH 3 group at 861 cm –1 . ,− The features of −CH 2 and C–F groups arise from the ODA and PVDF, respectively; the C–Si and Si-CH 3 groups result from the PDMS; and the C–C group originates from the long carbon chains in both the ODA and PVDF. After plasma treatment, the intensities of the features of −CH 2 , C–F, C–C, Si–C, and Si-CH 3 groups obviously decrease, indicating the drop of the contents of these groups.…”

Superhydrophobic coating with a micro- and nano-sized MnO2/PDMS composite structure for passive anti-icing/active de-icing and photothermal applications

“…No obvious coating blocks were observed to fall off after removing the 3 M tape, and the adhesion level of the coating could be categorized as level I according to the standard GB/T9286. 57,58 After several episodes of tape-stripping, the water droplets still good hydrophobic properties on the coating surface. However, on the platform with a small angle tilt (Fig.…”

Robust and Durable Superhydrophobic Coatings with Antipollution Flashover Performance via Silane-Modified Polyurea

“…In recent years, advanced superhydrophobic coatings have been developed with intrinsic self-cleaning properties, allowing water droplets to easily slide off the surface of the insulators, taking dirt with them. − Coating the insulators with a superhydrophobic surface is believed to be probably one of the most effective ways to prevent flashover, which has attracted the attention of a few scientists. − For instance, Tu et al investigated the impact of TiO 2 /epoxy coatings and observed that the coated film effectively suppressed charge accumulation . Du et al employed nonlinear conductive fillers, including micrometer-sized SiC, within composite coatings to enhance charge dissipation by tuning surface conductivity .…”
