The reason why lotus leaf has superhydrophobicity is that it has a micro - nano composite structureformed by surface papillae and waxy crystals .

The reason why lotus leaf has superhydrophobicity is that it has a micro - nano composite structureformed by surface papillae and waxy crystals .

Therefore, it is believed that there are twoways to construct a superhydrophobic structure :one is to change the surface roughness of the hydrophobic material ; theother is to modify the surface of the hydrophobic material with a certain surface roughness to modify low surface energy substances on the basis of the research on the lotus leaf structure.

Yang Jinxin and others discovered that the "strawberry" structure of SiO2 coated CaCO3 composite particles can prepare a coating with a "lotus effect".

Pawel Zylka uses electrical discharge machining to make a lotus-like structure template on the aluminum alloy plate, which can be used on the surface of the silicone rubber coating to construct the surface roughness of the coating.

Although this kind of method is operable, its process is complicated, the success rate is low, the cost is high, and it is difficult in actual operation.

Concluding remarksConcluding remarks

By analyzing the composition of the room temperature vulcanized silicone rubber anti-pollution flashover coating (usually including room temperature vulcanized silicone rubber, fillers, additives )and the role of each component, respectively, from the coating’s hydrophobicity, hydrophobic migration, and loss and recovery of hydrophobicity The performance of the coating was evaluated in terms of main indicators such as capacity and adhesion.

It is pointed out that the performance and life of the currently widely used anti-pollution flashover coatings can no longer meet the needs of power lines, and the development of a new type of long-term anti-pollution flashover coating with excellent performance is the best means to improve the reliability of external insulation.
