Synthesis and Solution Properties of New Polysiloxane Bola Surfactants Containing Carbohydrate.

Three polysiloxane bola surfactants containing carbohydrate (ATPS-LA) were synthesized using a two-step method. Structure characterization was performed by infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance spectroscopy (1H NMR). Their surface activities and aggregation properties in aqueous solution were investigated by surface tension measurements and transmission electron microscopy (TEM). The results indicated that these three surfactants have much higher surface activity than those of conventional hydrocarbon bola surfactants, such as sodium eicosanedioate, in aqueous solution, and they can self-assemble into spherical micelles with average diameters in the range from 100 to 600 nm.
