نبذة مختصرة : This study investigates the effects of epoxy coating and heat treatment on the surface wettability of Gigantochloa scortechinii bamboo in marine environments with varying seawater salinity. Bamboo strips were heat-treated at 160ºC, 170ºC, and 180ºC, followed by single and double layers of epoxy coating. Analyses of chemical changes and microstructures were performed using ATR-FTIR and FESEM. Surface wettability was evaluated through contact angle measurements. The results showed a reduction in bamboo hydrophilicity at 180ºC, as well as smoother surfaces and altered chemical compositions in treated specimens. Double-layer epoxy coatings provided better surface protection against water exposure. Increased hydrophobicity was observed with higher treatment temperatures, particularly at 180ºC. Additionally, bamboo surfaces in 100% saline solutions demonstrated higher wettability compared to 50% and 0% salinity levels. These findings indicate that the combination of 180ºC heat treatment and double-layer epoxy coating enhances bamboo’s hydrophobicity, making it more suitable for marine applications.
