摘要

This study presents the development of polyurethane (PU) based tin oxide (SnO2) nanocomposite coatings for hydrophobic surfaces and enhanced solar-driven photocatalytic behavior. SnO2 nanoparticles are synthesized via a hydrothermal method and uniformly incorporated into a polyurethane matrix to fabricate transparent, durable nanocomposite coatings. The structural and morphological characteristics of the coatings are analyzed using XRD, FTIR, SEM, AFM, and TEM, confirming strong interfacial interactions between SnO2 and PU matrix. The adhesion of the coating to the substrate was evaluated using the standard Scotch tape test. The wettability measurements revealed a significant increase in the water contact angle, indicating enhanced hydrophobic and anti-wetting behaviour of the surface. The photocatalytic performance of the coating is evaluated by measuring the degradation of an aqueous solution of Methyl Orange (MO) dye under sunlight. The synergy between the hydrophobic PU matrix and the photocatalytic property of SnO2 nanoparticles offers a multifunctional coating suitable for self-cleaning applications.
