Hexamethyldisiloxane (HMDSO) is one of the common promoter of making hydrophobic surface for its low surface energy character but its thin film is really poor in strength. On the other hand (3-Aminopropyl)triethoxysilane (APTES) is one of the most used silanes for its covalent characteristic. Due to its covalent characteristic, its surface energy is higher than HMDSO which makes surface hydrophilic. To make robust thin film on glass surface at atmospheric pressure these two precures were used at different proportions by non-thermal dielectric barrier discharge (DBD) plasma jet. The goal of the work to fine optimum mixture of these two precursors that will make robust hydrophobic thin film on glass surface. AFM, SEM, FTIR, XPS, WCA and scratch test were done to analyze the coating. Only HMDSO plasma coating on the glass surface was achieved WCA of 162 degree but only APTES was achieved WCA of 47 degree. |
