Design Development and Characterization Super Hydrophobic Surface Coating on Wood Materials

Abstract

Reliable PDMS and aluminum NPS coating have been developed to protect the wood from deterioration and other water-absorbing materials in humid conditions. Thus, alumina that readily available was utilized to make a harsh surface, which afterward combined chemically with PDMS to develop the hydrophobic characteristics. A few substitute layers of PDMS together with alumina particles were established to ensure hydrophobic properties, and the water impact and emery paper tests were investigated. The glass substrates and other hydrophilic materials were used to apply the coating to limit its water absorption. The coated wood that developed super-hydrophobic properties was examined by difference and change in contact angle by analyzing the level of water absorption in covered and uncovered wood samples.
