International. Scientists from China conducted a new study dealing with the easy design and manufacture of highly transparent and hydrophobic coatings on glass with anti-scratch properties through surface dehumidification.
Highly transparent hydrophobic coatings with scratch-resistant properties attract great interest from both scientific research and practical applications. A new study shows that hydrophobic coatings with high transmission performance and anti-scratch on glass substrates can be easily created by large-scale faded epoxy structures, followed by the bonding of a low-surface energy material. The influence of epoxy solution concentrations on dehumidified structures on the surface was investigated, as well as the hydrophobicity and transmissivity of glass substrates.
The concentration of the 5% epoxy solution combined with a coating of low surface energy material on the glass was found to exhibit the highest contact angle of ~113°. UV-vis spectrum studies indicated that the coatings manufactured by the new method had almost the same transmittance as that of the glass substrate.
In addition, the nano-scratch test illustrated that the prepared coating was capable of delaying the generation of cracks, further strengthening the glass surfaces. In addition, the approach also facilitates the large-scale manufacture of anti-scratch hydrophobic coatings on glass, as demonstrated by the preparation of screen coverings for mobile phones.
The detailed mechanism of large-scale hydrophobic coatings on glass with high transmission and anti-scratch performance was carefully crafted.
