| 目的 为缓解市场对聚酰亚胺的迫切需求，制备聚酰胺酸前驱体溶液和聚酰亚胺薄膜，并讨论工艺参数对聚酰亚胺特性黏度的影响。 方法 分别采用两步法和热亚胺化制备了聚酰胺酸前驱体溶液和聚酰亚胺薄膜，对单体配比、反应温度、反应时间及体系含水量等工艺参数进行优化实验，并通过乌氏黏度计、红外光谱仪（FTIR）和 X 射线衍射仪（XRD）对聚酰胺酸和聚酰亚胺薄膜的黏度和结构进行表征研究。 结果 优化后的工艺参数为： BTDA/ODA 摩尔比 1.02，反应温度 20 ℃， 反应时间 4 h，体系含水量 0%。由此制得了黏度较高的聚酰胺酸溶液，并通过热亚胺化制备了结构完整的聚酰亚胺薄膜。 结论 制备的聚酰亚胺薄膜均一、透明，具有完整的组织结构。 |

| Objective In order to relieve the urgent demand of market of polyimide, polyamic acid and polyimide films were prepared, and the effects of different parameters on the intrinsic viscosity of polyamic acid were discussed. Methods Polyamic acid solution (PAA) and polyimide films were prepared by two-step method and thermal imidization, respectively. The parameters of the monomer ratio, the reaction temperature, the reaction time and the water content in system were optimized by experiments, and the intrinsic viscosity and the microstructure of polyamic acid and polyimide films were characterized by ublelohds viscometer, Fourier transform infrared spectroscopy（FTIR） and X-ray diffraction （XRD） . Results The optimized parameters were: the monomer ratio BTDA/ODA of 1.02, the reaction temperature of 20 ℃, the reaction time of 4 h, the water content in system of 0%. Under this condition, polyamic acid solution with high intrinsic viscosity was obtained, and polyimide films with intact structure were prepared by thermal imidization. Conclusion The polyimide films prepared were homogeneous and transparent, with integrated structure. |
