Abstract

Abstract: Three glucosamide‐based polysiloxanes (GAPS) surfactants were prepared by amidation of gluconolactone with amino functional polysiloxanes synthesized by polymerization. GAPS were characterized by FT‐IR, 1 H NMR and 13 C NMR. Surface activity and aggregation behavior in aqueous solution were studied by surface tension measurements, dynamic light scattering and transmission electron microscopy. GAPS can reduce the surface tension of water to 24 mN m −1 at concentration levels of 10 −4 g mL −1 and self‐assemble in water at room temperature to form spherical micelles with average diameters ranging from 30 to 1000 nm. The micelle diameter increases with increasing degree of polymerization. Graphical abstract:
