Synthesis of cleavable silicone surfactant for water-repellent application

Polymeric silicone-based surfactants were prepared by the reaction of polyethylene glycol, maleic anhydride, polydimethylsiloxane, silicone oil, titanium isopropoxide, and sodium hydrogen sulfite. These surfactants showed water-repellent properties when cleaved by different buffer solutions. The synergetic effect of silicone oil-based surfactants and siloxane-based surfactants was studied using different characterization techniques for the surfactants. The hydrophobic properties of cleaved silicone-based surfactants were studied by measuring the contact angle measurement. The polymeric silicone surfactants are stable in nature. The structures of various stages of reaction were confirmed by thin-layer chromatography, Fourier-transform infrared spectroscopy, ultraviolet spectra, and nuclear magnetic resonance analysis. The surface-active properties of surfactants like surface tension and critical micelle concentration as well as foaming and wetting characteristics were also studied. This water-soluble surfactant had low foaming properties and can be used in textile, agriculture, petroleum and paint industries. The cleaved form of silicone surfactant was used for water-repellent application in textile and paint industries.
