Abstract In this work, the glass surface was successfully modified via low-temperature annealing and wet etching techniques. Hydrophilic/superhydrophobic of the modified glass surface was then transformed after dipped with methyltrichlorosilane (MTCS). Morphology and structural properties of the samples were analyzed by scanning electron microscopy, atomic force microscopy, fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The results exhibit that micro/nano roughness was observed on the annealed/etched glass surface. Interestingly, the wettability of the annealed and etched glass abruptly transformed to superhydrophobic with a water contact angle of 154° and a sliding angle of 3° after coating with MTCS. Annealing assisted etching technique not only plays an important role in changing of roughness in nanoscale by reducing residual and hardness but also changes the formation of polysiloxane from microspheres to nanofilaments on the surface.

一种使玻璃表面超疏水的简便方法

摘要 在这项工作中,通过低温退火和湿蚀刻技术成功地对玻璃表面进行了改性。改性玻璃表面的亲水/超疏水在浸入甲基三氯硅烷 (MTCS) 后发生转变。通过扫描电子显微镜、原子力显微镜、傅里叶变换红外光谱和X射线光电子能谱分析样品的形貌和结构特性。结果表明,在退火/蚀刻的玻璃表面上观察到微/纳米粗糙度。有趣的是,退火和蚀刻玻璃的润湿性在涂上 MTCS 后突然转变为超疏水性,水接触角为 154°,滑动角为 3°。
