ABSTRACT
Self-cleaning surfaces are developed through the use of superhydrophobic and water-repellent surface for glass coating applications. In the present study, anew copolymer of styrene-vinyl acetate (PS-VAc) has been synthesized. Furthermore, SiO2-NPs ranging from 90-100 nm were synthesized via sol-gel method. To increase the hydrophobicity, silane coupling agent namely dodecyl triethoxysilane (DTES), is used to prepare a hydrophobic modified SiO2-NPs with different concentration (1%, 3% and 5%). New super-hydrophobic nanocomposite are prepared through incorporation of the modified SiO2-NPs inside the prepared copolymer matrix donated as D-composites. We Investigated SH films using many techniques such as Fourier transform infrared spectroscopy)FT-IR), transmission electron microscopy (TEM), and dynamic light scattering (DLS), contact angle and Thermogravimetric analysis. Increasing the concentration of D-composite in the coated glass film improves the repulsion force between the water droplet and the coated film, the final contact angle of the coated film increases from 108.89 ±20o (hydrophobic in nature) to 150o (superhydrophobic in nature) with increasing the concentration of D-composite from 1 to 5 wt., %, respectively. From the obtained results, it is revealed that D-composites have distinguishable results to use it as a good water-repellent glass surface. Thus, a promising self-cleaning nanocomposite material was approved with superhydrophobicity and economic savings for glass surfaces.
