Deposition and evaluation of hydrophobic coating by wiping method

A modest, low-cost and time-saving method for preparing self-cleaning hydrophobic coating using wiping technique is reported in this paper. Commercially available hydrophobic solution was deposited on the sodalime glass substrate. By implementing the uniform wiping with a microfiber cloth, a water contact angle of 110.49° and transmittance value of 93% were obtained. The prepared coated glass presented good self-cleaning and able to maintain the efficiency of the coating under the performance test by rain droplet simulator. The proposed approach could be used as an effectual strategy for assembling self-cleaning hydrophobic surfaces on the solar panel.
