Cellulose derivative porous membrane and method for producing the same |
| abstract |
(57) [Problem] To provide a cellulose derivative porous membrane having a high permeation flux of water and a good fractionation performance. SOLUTION: The porous membrane obtained from a cellulose derivative has pores on the surface and inside, and the pores on at least one surface have an average pore diameter of 0.1 to 20. In μm, the pores existing inside the film are formed uniformly from one surface to the other surface, and the average pore diameter of the pores on the surface relative to the maximum average pore diameter (A) of the pores inside the film. A cellulose derivative porous membrane having a pore diameter (B) ratio (B / A) of 0.2 to 5.0. |
