推导出了整个扩散区的扩散方程和动态吸附初期的吸附方程 ,实验研究并分析了CH2 Cl2 、CH3OH、CH3CH2 OH和H2 O 4种渗透物小分子在不同厚度的聚酰亚胺高聚物膜内的动态吸附行为 ,并计算出了反常扩散指数dw.
The diffusion equation of the entire diffusion zone and the adsorption equation at the initial stage of dynamic adsorption were deduced. The effects of the permeation of CH 2 Cl 2, CH 3 OH, CH 3 CH 2 OH and H 2 O on the thickness of the polyimide polymer film Within the dynamic adsorption behavior, and calculated the anomalous diffusion index dw.
