A convenient tape-casting method was applied to prepare high performance aromatic polyamide (PA) films based on Technora®. During the polycondensation, CaO was introduced to improve the solubility of the PA resin, and the generated halides were totally removed from the film via a simple water bath, without leaving any defects in PA films. The factors of processing temperature and immersion time had been systematically investigated, and the experimental results demonstrated that both of them had impressive impacts on aggregation state and comprehensive properties of the PA film. It was suggested that immersion in water for more than 1 min and baking below 300 °C for 10 min were the optimal conditions for the thermal, tensile, tear, and optical properties to be in the best equilibrium. The resultant PA films integrated outstanding film-forming ability and excellent general performance, especially the tensile property and tear resistance.

应用一种方便的流延法来制备基于Technora®的高性能芳族聚酰胺（PA）薄膜。在缩聚过程中，引入CaO以改善PA树脂的溶解性，并且通过以下方式从薄膜中完全去除了生成的卤化物简单的水浴，不会在PA膜上留下任何缺陷。系统地研究了加工温度和浸泡时间的影响因素，实验结果表明它们对PA薄膜的聚集态和综合性能均产生了显着影响。建议将其浸入水中1分钟以上，并在300°C以下烘烤10分钟是使热，拉伸，撕裂和光学性能达到最佳平衡的最佳条件。所得的PA膜具有优异的成膜能力和优异的综合性能，特别是拉伸性能和抗撕裂性。
