疏液表面在工业生产和日常生活中有着非常广阔的应用前景，对材料的防粘附性、防污、延长使用寿命等方面都具有非常重要的意义。采用喷丸处理、化学刻蚀及低能修饰相结合的方法在 X70管线钢基体上成功制备了疏液表面，并用扫描电子显微镜、共聚焦显微镜、能量色散 X射线光谱仪和接触角测试仪对管线钢表面的微观形貌、化学成分和润湿性进行了分析。结果表明，亲液的微纳米粗糙结构表面经过低能物质修饰后变为疏液甚至是超疏液表面，蒸馏水和花生油在疏液表面的最大接触角分别为150和140°。

Lyophobic surfaces have extremely broad application prospects in industrial production and daily life, and have very important significance on the preventing adhesive of materials,anti-fouling,and prolonging serv-ice life.In this article,lyophobic surface on X70 pipeline steel was fabricated successfully via the combination of shot peening,chemical etching,and low energy modification.The surface morphology,chemical composition, and wettability were studied by scanning electron microscope,confocal microscope,energy dispersive X-ray spectrometer,and contact angle tester.The results show that,the lyophilic surfaces with micro-nano structure changed into lyophobic or super-lyophobic surfaces after modified with low energy materials,and the maximum contact angles of distilled water and peanut oil were 150 and 140°,respectively.
