Abstract
-
Two series of cationic gemini surfactants with rigid and flexible spacer, respectively, have been synthesized.;Some abnormal phenomena of the equilibrium surface tension and related surface properties have been explained by the premicellar aggregation of aqueous solutions of these gemini surfactants. The interactions of the synthesized cationic gemini surfactants with conventional anionic and nonionic surfactants in monolayer formation and micelle formation have been studied.;The dynamic surface tension of solutions of the synthesized cationic gemini surfactants and calculation of the dynamic surface tension parameters showed that the spacers affect the dynamic surface properties.;There is no correlation between superspreading of solutions of trisiloxane surfactants and Draves skein wetting test. The synergism of superspreading of trisiloxane surfactant with some additives on Parafilm surface has no relationship with the dynamic surface tension.
