The dilational viscoelasticity properties of gas-water interface of SDBS were investigated. The dependence of dilational modulus, dilational viscosity and phase angle on dilational frequency was expounded. The results showed that the microscopic relaxation model of the surface film was decided by diffusion-control model. Besides, the influence of temperature and concentration to the interfacial dilational properties of SDBS was also discussed, and the intrinsic relation between them was studied.
