Tailoring the hydrophobicity of copper surface with ion beam irradiation

摘要: ABSTRACTDropwise condensation of water vapor present in moist air on copper surface is significant scientific interest worldwide, for developing an efficient condensing unit harvesting via dewing devices. However, it does not prolong a long duration these surfaces because the highly reactive nature copper. In this work, simple and economically viable methods are described altering morphology which exhibit dropwise duration. The durable hydrophobic fabricated by electrochemical deposition solution immersion chemically etched samples, followed ion beam irradiation 15 keV Ne ions at fluence 1017 ions/cm2. roughness tailored samples measured using atomic force microscope contact angle measurements performed measuring static deionized droplets modified surfaces. results show that irradiated have low angl...
