“…Gemini surfactants, also referred to as dimeric surfactants, consist of two hydrophilic heads and two hydrophobic chains that are connected by a rigid or flexible spacer. 1 Over the last two decades, they have attracted particular interest in different fields including material sciences, wastewater remediation, 2,3 surface treatment, 4,5 catalysis, 6,7 analytical separation, solubilization and flotation processes 8 and paint additive industry. 9,10 Compared to conventional single-tail surfactants, they are more effective and can often attain much lower surface tension, critical micellar concentration and Kraft point values.…”
