Development of novel anti‐wetting coating on cellulosic surface using low carbon butyric acid

In this work, first time anti-wetting coating on wood surface is prepared by using titanium dioxide (TiO2) nanoparticles and low carbon chain fatty acid (butyric acid). By combining TiO2 nanoparticles and butyric acid, superhydrophobicity is achieved with water static contact angle of 168 ± 2° and tilt angle of 6 ± 1°. Coating exhibits the excellent anti-dust and anti-stain properties. Coating is found to be mechanical, thermally, UV and chemically stable after performing water jet, sand abrasion, annealing, sun light exposure and chemical stability tests. Additionally present study also shows that coated surface attains sticky superhydrophobicity at high impact velocity. We envision that the durable superhydrophobic coating of TiO2 nanoparticles and butyric acid can be effective for anti-dust and anti-stain properties of wood surface and aforesaid coating has great industrial and household applications.
