| 摘 要： | 利用原子力显微镜（AFM）测定了不同凝固浴条件下制得的纤维素膜的表面形貌，通过分析膜表面孔径大小和分布发现，Lyocell膜表面的平均孔径随着凝固浴温度和凝固浴中NMMO浓度的升高而增大，且径孔分布有变宽的趋势。

| Abstract: | Cellulose/NMMO solution was immersed into water bath with various NMMO content under different bath temperature. The AFM method was used to analyze both size and distribution of pores on membrane surface as well as the roughness of the skin. It was found that the surface pore size increases and the pore size distribution becomes wide with the increasing of both temperature and NMMO content of coagulation bath. |
