I学士学位论文论文题目:聚酰亚胺膜的制备作者:吕厚为指导教师姓名:胡知之专业名称:化学工程与工艺辽宁科技大学本科生论文第1页摘要本实验以6FAPB与通过用不同次数重结晶的CBDA及不同回流次数的CBDA作原料,DMAC为原料在机械搅拌,冷水浴保护条件下合成聚酰胺酸(PAA)溶液,涂膜后通过热酰亚胺化方法得到聚酰亚胺(PI)薄膜。然后,利用紫外-可见光谱(UV)、红外光谱等方法对PI膜材料的结构与性能进行表征,实验结果表明,经过重结晶的CBDA透明性更好,聚合度更加,性能更加优异。关键词:CBDA;聚酰亚胺;结构与性能;薄膜AbstractInthispaper,undertheconditionofmechanicalagitationandthecoldbath,wesynthesizedpolyamideacid(PAA)solutionwithp-6FAPBandCBDAasrawmaterialandDMACassolvent,inwhichCBDA(cyclobutanedianhydride)wasproducedbyphoto-dimerizationreaction,aftercoatingweobtainedpolyimide(PI),weusedultraviolet-visiblespectroscopy(UV),,morepolymerizationdegree,:CBDA;Polyimide;Structureandperformance;film目录摘要............................................................................................................................................................2ABSTRACT.....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................…………………………………………………..................................................................................................................................................................................................................................................
