用Voigt蠕变模型和Flory-Huggins混合模型分别计算溶剂在高分子膜中吸收和解吸过程高分子的蠕变及与溶剂混合的吉氏函数变化,结合质量守恒建立了一个小分子在玻璃态聚合物中吸收和解吸的传递模型,模拟计算结果和对实际系统的吸收和解吸曲线的关联和预测结果表明,模型能很好地描述实验中常遇到的S形吸收曲线,并能根据吸收曲线的实验信息预测相应的解吸曲线。与Crank模型比较,此模型具有参数少而灵活的优点。 The Voigt creep model and the Flory-Huggins mixture model were used to calculate the creep of the polymer during the absorption and desorption of the polymer in the polymer membrane and the change of the Giemsa’s function with the mixture of the solvents. A mass- The model of absorption and desorption, the simulation results and the correlation and prediction of the absorption and desorption curves of the actual system show that the model can well describe the S-shaped absorption curves commonly encountered in experiments and can be used to predict the absorption and desorption curves according to the absorption curve Experimental information predicts the corresponding desorption curve. Compared with the Crank model, this model has the advantages of less parameters and more flexibility.
