Abstract:
Two new anionic silicone surfactants were synthesized for the first time from dichloromethylvinylsilane or trichlorovinylsilane through hydrolysis-condensation and then thiol-ene reactions. Their structures were characterized by FT-IR, 1 H NMR and ESI-MS. The surface tension (γ), critical aggregate concentration (CAC), surface pressure at CAC ( ) and minimum surface area per surfactant molecule ( ) were studied by surface tension and electrical conductivity, demonstrating their high surface activity at the gas/liquid interface. Transmission electron microscopy measurements showed that uniform spherical aggregates former in aqueous solution for both surfactants. Moreover, the size of the aggregates was determined to be in the range from 50 to 300 nm by dynamic light scattering.
