Contact angle relaxation studies were performed on a base hydrolyzed PMDA-ODA polyimide surface using methanol, pyridine and 1-methyl-2-pyrrolidinone (NMP) as probe liquids. The results were fitted parametrically to the molecular-kinetic theory to obtain the relevant molecular parameters that govern wetting rates. The probe liquid NMP appeared to have the greatest interaction of the three solvents studied with the modified polyimide surface. The differences in wetting rates are explained to result from the hydrogen bonding capability of the probe liquids with the modified polyimide surface and due to the difference between bulk and surface pKa of the modified polyimide.
使用甲醇、吡啶和1-甲基-2-吡咯烷酮（NMP）作为探针液体，对碱水解的PMDA-ODA聚酰亚胺表面进行了接触角松弛研究。结果通过参数拟合到分子动力学理论，以获得控制润湿速率的相关分子参数。在所研究的三种溶剂中，探针液体NMP与改性聚酰亚胺表面的相互作用似乎最大。润湿速率的差异被解释为是由于探针液体与改性聚酰亚胺表面的氢键能力，以及改性聚酰亚胺本体和表面pKa之间的差异所致。
