| dc.description.abstract | Polymer composites are increasingly used in outdoor applications. However, their long-term performance is compromised by moisture absorption and weather-induced degradation. There is a critical need for coatings that can maintain hydrophobicity and mechanical robustness. This study aims to develop hydrophobic polyurethane (PU) nanocomposite coatings reinforced with multi-walled carbon nanotubes (MWCNTs), graphene, and silica (SiO₂) using a dip-coating technique, focusing on focusing on the effects of filler type, concentration, silane treatment, and accelerated weathering on wettability and performance. The samples were characterized based on tensile, wettability (WCA), friction test and morphology. Results showed that 5 wt% filled MWCNT achieved the highest tensile strength (11.46 MPa) and WCA (120.08°) compared to other nanocomposites coatings. Silane treatment enhanced filler dispersion and interfacial bonding, enabling nanocomposite coatings to retain higher hydrophobicity (127.7°) and structural integrity after accelerated weathering compared to untreated systems. Overall, treated 5 wt% filled MWCNTs offer durable protection for composite substrate by combining enhanced hydrophobicity, mechanical robustness, and environmental resistance. | |
