Abstract: Abstract A nonlinear diffusion equation is used to study early‐stage spinodal decomposition of polymer solutions, in relation to the membrane formation, in two dimensions. The effects of overall polymer composition and composition‐dependent mobility and diffusivity are included in our simulations. Our results show a kinetically stable structure is established during the early stages, which corresponds to a circular range of peaks in the two‐dimensional frequency spectrum. Such a spectrum is found to result in …
