AB - The three-step upright cup method was employed to determine the total  moisture transfer resistance and the two air layer resistances on both sides  of the membrane. The effective moisture diffusion coefficient in air layer  between the membrane and water surface was determined by the regressive  method, and the effective moisture diffusion coefficient of membrane was  calculated. Experiments were conducted on a non-porous hydrophilic  thermoplastic polyester elastomer membrane. The moisture transfer process  through the membrane was modeled by using the solution-diffusion model. The  effects of membrane microstructure on membrane permeation were analyzed based  on the solution-diffusion model and experimental data. The results show that  the effective diffusion coefficient can be used to evaluate the mass transfer  process through the non-porous hydrophilic thermoplastic polyester elastomer  membrane.
