Effect of temperature on the wettability of CuO nanowires

CuO has been prepared by a thermal method in different temperature 300-600°C, the water contact angles of CuO film were measured by the contact angle goniometer; the contact angles were investigated to see the effect of temperature on the wettability of the CuO film which was found to be hydrophilic in nature. The copper before treatment is hydrophobic then, it changed to hydrophilic after the treatment in different temperature.
