PS binary porous structure membrane with big pores on the surface and small pores in the bottom was prepared combine BF method and colloidal crystal template method. Therefore, the big pore size can be controlled by BF conditions, while the small size adjusted by SiO2 particles size. Compared with membrane prepared only using BF method, the binary porous structure membranes with high permeability possess potential applications in microfiltration.
