| Abstract: | Abstract A lactobionamide-based trisiloxane surfactant (Si3N2–LA) was prepared via a two-step method. Structure characterization of Si3N2–LA was performed by Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (1H NMR). Surface activity and aggregation behavior in aqueous solution of Si3N2–LA were investigated by surface tension measurements, dynamic light scattering (DLS) and negative-stained transmission electron microscopy (TEM). The results show that the surfactants can self-assemble into spherical vesicles with diameters in the range from 50 to 150 nm due to the introduction of trisiloxane tail. |
