摘 要：The effects of modifiers on the anti-wetting and anti-icing property of the prepared rough aluminum surface were investigated.The rough aluminum substrates were obtained through electrochemical oxidization with 15 wt% sulfuric acid solution as the electrolyte at the constant current of 4 mA for 3 h.And then they were modified with octadecanoic acid （C18）,polyethylene （PE）,polystyrene （PS）,polyethylene glycol （PEG） and hexamethylenetetramine （HMTA）,respectively,whose surface free energies were 27.6,31.0,33.0,61.6 and 70.0 mN/m,respectively.The contact angles （CA） were 154.6°,128.4°,127.6°,5.0° and 0.0°,respectively,and the ice adhesion pressures were 15.9,36.3,55.9,155.3 and 216.1 kPa,respectively.The ice adhesion strengths decrease along with the increasing anti-wetting property of aluminum surfaces and the decreasing of the surface energy of modifiers.These provide some new insights when designing the aluminum surface with anti-icing properties in some special applications.
