摘要

This work aims to fabricate new potent superhydrophobic-hybrid coated nanocomposites used as a self-cleaning coating on the glass surface. Three (styrene/vinyl acetate) copolymers with monomer molar ratios of 0.06:0.17, 0.12:0.11, and 0.17:0.06 denoted as Z1-, Z2-, and Z3-copolymers were synthesized using the emulsion phase inversion concentration (EPIC) method. Two functionalized SiO2-NPs using dodecyl triethoxysilane and hexadecyl trimethoxysilane as coupling agents denoted as E-NPs and F-NPs, respectively were fabricated by a sol-gel process to promote the hydrophobicity properties of the synthesized SiO2-NPs. New hybrid composites denoted as P-y and T-y(y = 1, 2, and 3) were fabricated by incorporating 1, 3, and 5 wt of the functionalized SiO2-NPs (E-NPs or F-NPs) into the Z3-copolymers matrix, respectively. The chemical structures of the synthesized copolymers, unfunctionalized SiO2-NPs, and the hybrid composites were elucidated by FTIR and (HNMR)-H-1 spectroscopes. The surface wettability and topography of the glass-surface coated by synthesized (styrene/vinyl acetate) copolymers and the silica hybrid composites were analyzed using water contact angle, scanning electron, and atomic force microscopes. The results showed that a highly superhydrophobic coated hybrid composite with a contact angle of 161.48 degrees was achieved by Z3-copolymer/F5-NPs denoted as T3-composite at F5-NPs concentration of 5 wt.
