摘　　要：本文应用一步阳极氧化法在铝表面制作纳米粗糙结构的超亲水表面.考察控槽压、控电流及氧化时间对氧化铝表面超亲水性的影响.测试表明,控电流法更有利于制作超亲水表面,增大电流密度可缩短氧化时间,该法可制作稳定性好、机械强度高的超亲水氧化铝表面,富有潜在的应用价值.Hydrophilic aluminum oxide is popularly used for heat exchanger of air-condition. Herein, we developed a simple method to prepare superhydrophilic aluminum oxide on the surface of aluminum through single- step electrochemical oxidization. The morphologies and water contact angles on surfaces of alumina fabricated under different electrochemical conditions were investgated. Superhydrophilic surfaces fabricated by this method have good stability and high mechanical strength with water contact angle almost 0% Coated with low surface energy materials, superhydrophilc alumina will be converted to superhydrophobic.
