摘要
采用化学氧化和分子组装等方法对铜粉进行改性后,再通过压制成型工艺,设计研发了一种接触角可达153.2°、滚动角小于7°的新型铜基超疏水材料。通过X射线衍射、红外光谱分析、扫描电子显微镜观察和接触角测量对超疏水铜基材料的相结构和表面化学结构、形貌和润湿性能进行了表征及分析。研究结果表明：具有疏水性的烷基长链成功组装到了具有手指状微纳结构的铜基材料表面,从而赋予铜基表面具有超疏水特性。这种铜基超疏水材料经过表面打磨、在空气中放置一年以及在水中长时间浸泡后,其表面仍然保持良好的超疏水特性。同时,该超疏水材料在较宽的p H值范围内（p H=2~12）可以保持良好的疏水性能。
A novel copper-based superhydrophobic material was designed and developed via compression forming of the modified copper powder which was treated by techniques of chemical oxidation and functional graft. The phase structure,chemical structure,morphology,and wettability of the superhydrophobic material were investigated by XRD,FT-IR,SEM,and contact angle measurement,respectively.The results show that the contact angle of the resultant superhydrophobic sample can reach 153. 2° while the rolling angle is below 7°; the copper-based superhydrophobic surface has the finger-like micro-and nano-structure,and the long alkyl chains are successfully selfassembled onto the finger-like surface. Consequently, the copper-based surface wins the superhydrophobicity. The copper-based superhydrophobic surface still maintains the superhydrophobicity after surface sanding,placed in the air for a year,and soaking in water for long time. Meanwhile,the superhydrophobic material can also maintain excellent water repellence in a wide p H range（ p H = 2- 12）.
