Fabrication of C-Doped Titanium Dioxide Coatings with Improved Anti-icing and Tribological Behavior

Abstract

The accumulation of ice on solid surfaces can cause serious losses and accidents. Current anti-icing/deicing coatings find it difficult to maintain their properties under frequent mechanical wear. In this work, the aerosol-assisted chemical vapor deposition method was employed to prepare C-doped titanium dioxide coatings that have both photothermal properties and excellent wear resistance. The temperature of the sample surface reached 37.6 °C after 2 sun (2 kW/m2) irradiation for 30 min at −30 °C. Compared to a pristine titanium dioxide coating, the C-doped titanium dioxide coatings demonstrated superior antifriction behavior, with the friction coefficient reduced by 47% under dry conditions. These wear resistance properties make C-doped titanium dioxide coatings highly suitable for a range of outdoor applications, especially for anti-icing purposes.

Photo-Thermal Superhydrophobic Sponge for Highly Efficient Anti-Icing and De-Icing

“…During warm daytime, enough heat is generated by solar-thermal conversion to keep the temperature of the coating surface above zero to achieve anti-icing and de-icing. On a cloudy day or extremely cold day, the coating can also stay warm to prevent icing owing to photo-thermal and electric-thermal dual effects. , In addition, other photo-thermal materials, such as ferriferrousoxide, , polypyrrole, SiC, TiO 2 /C, Ti3C2T x MXene, and ZnSb, were also used to prepare photo-thermal deicing coatings. For photo- or electric-thermal de-icing materials, reducing the heat loss was first considered due to the close correlation of de-icing efficiency.…”
