Synthesis, characterization and surface properties of amino-glycopolysiloxane

Three series of amino-grafted polysiloxane surfactants with well-defined amphiphilic structures, were successfully synthesized and characterized by FT-IR and 1H NMR. Their surface activities and aggregation behavior in aqueous solution were investigated by surface tension measurements for different concentrations at 25 ℃. Various surface properties of the synthesized surfactants, particularly interfacial tension, foaming power, emulsification power and surface parameters like, critical micelle concentration (CMC), effectiveness (πCMC), efficiency (PC20) as well as maximum surface excess (Γmax) and minimum surface area (Amin) were evaluated. Micellization and adsorption in liquid/air interfaces thermodynamics were investigated. All compounds prepared showed good surface properties, surface parameters and thermodynamic parameters.
