Abstract本发明涉及高分子分离膜技术,具体地说是含有柔性链段聚醚的聚酰亚胺膜材料及均质膜的制备方法,在15~30℃氮气气氛中,将芳香族二胺单体和二端胺基聚醚溶解在极性溶剂中,加入芳香族二酸酐;搅拌反应10~24h后;加入催化剂和吸水剂,继续反应10~24h,然后升高温度到50~90℃反应1~5h;最后使聚合物在沉降剂中沉降,得到的聚合物在真空烘箱中80~120℃烘24~48h;将得到的聚合物材料溶解在极性溶剂中,把溶液倒在聚乙烯板上,25~60℃下干燥成膜,得到的均质膜,然后把膜放入真空烘箱中80~120℃烘24~48h;得到的膜厚度在50~150μm之间。本发明以聚醚柔性链段加入刚性聚酰亚胺主链中,得到了具有优异CO2气体分离性能的均质膜。; 带填写
