Silane Coupling Agent Effect on the Surface Modification of Titanium

摘要:

采用浸渍法将NaOH碱处理后的钛片浸入硅烷溶液中进行表面改性，可制备致密硅烷瞙。利用SEM、FTIR、EDS、表面接触角分析仪等研究硅烷膜的表面形貌与结构特征。结果表明：不同浓度的硅烷溶液对硅烷膜的表面形貌、表面接触角以及表面基团的组成有较大影响；将钛片浸入浓度33％的硅烷水解溶液中，所制备的硅烷膜较完整，由许多呈脑浆状的小片构成，排列紧密，含有硅醇Si-OH和Si-O-Si 网络结构，其表面接触角为71.8°

Abstract:

The titanium plates modified by NaOH alkali solution were immered into silane solution to prepare compact silane films on titanium substrate. The characteristics of the silane films were investigated by SEM, FTIR, EDS and surface contact angle analyzer. The results show that the different concentrations of silane solutions have greater effects on the surface morphology, the surface contact angle and the composition of surface groups of the silane film. The integrated silane film with lots of small close packing pieces is made as the samples dipped into silane solution with a concentration of 33% and surface contact angle of 71.8 °
