| Abstract: | The unsymmetrical cellulose membrane was prepared by NMMO technology and phase trans- formation method. The effect of casting speed on the structure of membranes was studied. The results showed that with increasing of casting speed, the cellulose membrane has lower roughness, larger crystallinity, and higher degree of orientation. The purpose was to provide theory basement for optimizing the processing parameter, controlling the structure, enhancing performance, and increasing the application range of the cellulose membrane prepared by NMMO technology. |
