Dimer is a new generation surfactant, which is a break-through to traditional surfactants. Dimeric surfactants are made up of two conventional surfactant moieties connected at the level of the head groups or very close to the head groups by a spacer group, which inhibits the separation of the head groups, strengthen the interaction among hydrophobic chains, and improve the surface activity greatly.
We have mainly investigated the synthesis and characterization of the environment friendly dimers—d...
