Description

technical field [0001] The invention relates to the technical field of photothermal conversion materials, in particular to a biochar-titanium nitride superhydrophobic photothermal coating material and a preparation method thereof. Background technique [0002] Large-scale icing has caused serious safety hazards to residents' lives and industrial production, such as icing of buildings, highways, power lines, aircraft and wind turbines, resulting in huge economic losses and even casualties. Traditional deicing methods mainly use electric heating, mechanical force or chemical reagents to deicing. However, these deicing methods have many disadvantages such as: they need to consume a lot of energy, the related equipment or systems are difficult to design, and they are usually not environmentally friendly. Recently, the use of photothermal superhydrophobic coatings for passive deicing has attracted great attention. Different from traditional deicing methods, photothermal superhyd...
