| Popis: | In this research study the fabricated of hydrophobic of SiO2 nanoparticles was modified with tetraethylorthosilicate (TEOS), poly-(dimethylsiloxane) (PDMS) and methyltriethoxysilane (MTES) by using a sol-gel method. The effects of precursors, coating techniques and curing conditions were investigated. A water contact angle (WCA) measurement done using a sessile drop method with an optical contact measuring apparatus. Morphologies of the hydrophobic films were depicted using scanning electron microscopy (SEM). All data were analyzed using Design Expert® software. Results shown that a morphology of hydrophobic films had nanoroughness as evidenced by high contact angle. The largest predicted WCA of these is 150.306 degrees, which will be obtained with a TEOS:SiO2:PDMS:MTES ratio equal to 7.00:3.374:2.75:3.00 wt.% respectively. It is coated using a dipping technique and oven cured at 400°C. |
