Effects of molecular structure on properties of gemini surfactants

The effects of various structure parameters of gemini surfactants such as nature of the hydrophilic head groups,nature and chain length of the hydrophobic tail groups,nature and chain length of the spacer groups,and nature of the counter ion et al.on their dissolution properties,surface activity,micelle morphology,foaming performance and lime soap dispersing power et al.were summarized.Gemini surfactants are a series of novel surfactants that have unique performances such as lower critical micelle concentration,high surface activity,strong viscosity boosting capability et al.These performances result in good application potentials.The important sense of the structure parameters of gemini surfactants on their specific applications was described.Their future applications were prospected.
