Special issue of JSD highlights recent work in Gemini surfactants

摘要

Gemini surfactants,an exciting new class of surfactants comprised of two surfactant mole-cules connected at or near the headgroup with a spacer,exhibit greater surface activity than conventional single-chain surfactants due to increased hydrophobic interaction with water.Their critical micelle concentration(CMC)and interfacial tension are typically much lower than those of conventional surfactants,and they show unique rheological properties and form worm-like micelles and vesicles at low concentration in water.
