Abstract
Inspired in nature, the fabrication of superhydrophobic surfaces without using fluorderivates which are harmful to both environments and humans is nowadays a major object of study. This study aimed at building dual-scale multistructure using low coat, green-based coatings to prepare superhydrophobic paper surface. Specifically, castor oil based biothiol which can be self-initiated under UV irradiation was used as the matrix resin. After mixed the resin with fumed silica nanoparticle at certain weight ratio, spray coating the mixture on the surface of papers. Then the coated paper was cured under UV irradiation. The obtained surfaces showed a multi-scale rough texture and an apparent water contact angle of 157.6 ± 1.3. Moreover, the coatings are able to withstand 5 cycles of abrasion without an apparent decrease of superhydrophobicity.
