文摘

Take didecyldimethylammonium carboxylate as model to study surface properties. Kinetics of adsorption at interface is different from conventional surfactants. The conduction properties' transformed carbon number is equal or greater than 6. The equilibrium and dynamic surface tension properties show a regular trend. Adsorption is controlled by diffusion-controlled and activated-diffusion.
