不锈钢表面双重纳米结构的构建及疏水性能研究

Construction and Hydrophobic Properties of Double Nanostructures on Stainless Steel Surface

采用电化学阳极氧化法结合盐酸腐蚀法在316LSS表面构筑双重纳米结构,进一步采用PTES进行修饰,构筑316LSS疏水表面,对其结构和形貌等进行全面的研究和分析。结果表明,316LSS表面成功构筑了双重纳米结构,纳米坑直径为(86±12)nm,纳米小颗粒的直径为(17±4)nm,PTES被成功修饰在316LSS表面,316LSS表面的接触角由76°±3°提高至106°±4°,且其抗菌性能也得到了提高。316LSS的改性制备有望为金属材料表面的进一步改性研究提供实验和理论依据。

The double nanostructures were constructed on 316LSS surface by electrochemical anodizing combined with hydrochloric acid etching,and the hydrophobic surface of 316LSS was further constructed by PTES modification.The results showed that the diameter of the nanopits was(86±12)nm and the diameter of the small nanoparticles was(17±4)nm.The PTES was successfully modified on the surface of 316LSS.The contact angle of the surface of 316LSS was increased from 76°±3°to 106°±4°,and improved its antibacterial performance.The modified preparation of 316LSS is expected to provide experimental and theoretical basis for further modification of the surface of metal materials.
