In order to reduce the impact of the external environment on the operation safety of transmission lines

a super-hydrophobic surface is successfully prepared on the insulator glass material and the aluminum material under the atmospheric pressure

by using a dielectric barrier discharge device of a needle-tube structure. The static contact angle of the surface reaches 165° and the rolling angle is lower than 3°. The plasma is driven by AC power and generated by the gas mixture of argon/HMDSN. The radiation spectrum shows that the silicone monomer is cracked and reacts with air to generate a large amount of C—H and C—O groups. The FTIR shows that the super-hydrophobic film contains a plenty of CH3 groups

and it has a nano-scale structure similar to the lotus leaf from the results of AFM and SEM analyses. Finally

the surface corrosion resistance to acid and alkali and the self-cleaning properties of super-hydrophobic surfaces have been investigated

the results show that the prepared super-hydrophobic film can effectively prevent corrosion of strong acid and alkali and has a certain anti-pollution ability.
