Synthesis and properties of new dicephalic tetrasiloxane surfactants containing sugar

A series of dicephalic tetrasiloxane surfactants containing sugar were synthesized. Their structure was confirmed by infrared spectroscopy and 1H nuclear magnetic resonance spectroscopy. Their surface activity and wetting ability on low energy substrates were also investigated. The results showed that the target surfactants exhibited excellent surface activity, which could reduce the surface tension of water to a minimum value of 20–21 mN m−1, and excellent wetting ability, which could completely wet parafilm.
