摘　　要：以二氨基二苯醚(ODA)、对苯二胺(PDA)为二胺单体,均苯四甲酸二酐(PMDA)为二酐单体,N,N-二甲基乙酰胺(DMAc)为溶剂,经共聚合反应得到聚酰胺酸。然后涂膜、亚胺化,得到聚酰亚胺薄膜(PI)。通过调节二胺单体的比例、聚酰胺酸树脂(PAA)黏度等因素,探究其对PI薄膜吸水率的影响。Diaminodiphenyl ether(ODA),p-phenylenediamine(PDA)are used as diamine monomers,pyromellitic dian⁃hydride(PMDA)is used as dianhydride monomers,and the solvent is N,N-dimethylacetamide(DMAc),the polyamic ac⁃id is obtained by copolymerization.Then the film is coated and imidized to obtain a polyimide film(PI).By adjusting the ra⁃tio of diamine monomer,imidization process,viscosity of polyamide acid resin(PAA)and other factors,the influence on the water absorption of the film was explored.
