Abstract

The observation of lotus leaves wettability behavior can be applied in various application. Silica has a good characteristic for hydrophobic stability. This objective of the study was to create a hydrophobic surface from a composite material of SiO2 filler and polydimethylsiloxane matrix. Silica is obtained from the purification of natural sand Bancar, Tuban, East Java. The variations of phases used were silica quartz (SQ), silica amorphous (SA), and silica cristobalite (SC). Silica cristobalite (SC) was obtained after calcinate SA at temperature 1200°C for 2 hours. The results of this research showed that the highest contact angle of hydrophobic surface is 126.4° (hydrophobic) at 400°C and the lowest is 72.4 (hydrophilic) at 500°C. The water contact angle (WCA) of the as-prepared hydrophobic coatings reached as high as 148.24° (WCA=148.24°) by applying of the PDMS/SA coating. The transmittance of coatings reached as high as 100%.
