A computer simulation study on the diffusion and permeation of dimethylformamide/water mixtures through poly(vinyl alcohol)/poly(acrylic acid) blend membranes

- The PVA/PAA blend membrane was suitable for separating the DMF/water.
- The energy barrier for water molecule permeating through the membrane was calculated.
- The process of separating the DMF/water could be divided into four different domains.
