This study was carried out to investigate the effect of treatment eastern cottonwood with nano-copper oxide on the surface roughness and contact angle. For this purpose, specimens with the dimensions of 50×50×2 mm (tangential × longitudinal× radial) were prepared from sapwood of eastern cottonwood followed by impregnating with nano copper oxide suspension (500, 1000, 1500 ppm). The obtained results showed that the most important roughness parameters exception Rv and Rvk significantly increased by treatment wooden samples using nano copper oxide. It is clearly verified this treatment amplified the surface roughness of wooden samples. The contact angles were also affected by treatment and had the same behavior as like surface roughness.
