Abstract Aluminum is the main material for the wings of the air conditioner, and hydrophilic aluminum is important to improve heat dissipation.In this paper, the hydrophilic aluminum surface was prepared by the reaction of aluminum with C6H12N4 solution.The influence of different drying temperature after reaction of aluminum with C6H12N4 solution on the surface product and contact angle were investigated.It was found that when the temperature was between 60—300 ℃, the surface formed Al(OH)3 with ball shape, and when the temperature was above 400 ℃, Al(OH)3 transformed to ε-Al2O3 with hexagonal structure.The contact angle(CA) and the stability of aluminum after reaction with C6H12N4 solution and drying at different temperature are determined to be all 0°, and still be 0° after one month.
