The principle of atomic force microscopy (AFM) and the method of determination of cellulose membrane were introduced, and the surface morphology of several cellulose membranes was measured.The results showed that AFM was very suitable for studying the surface topography of cellulose membrane, Analyzing the pore size and distribution on the surface of the cellulose film can better explain the change in the properties of the cellulose film
