研究了高分子微球复合水凝胶的应力-应变关系。本文的创新之处在于提出了基于微观混合熵和Flory-Reynner弹性能的应变-应力模型。最后给出了应力-应变模型的数值结果,该结果与化学实验结果完全一致。此外,理论上的应力-应变关系依赖于MMC水凝胶的微观参数。因此,这是一种研究软物质宏观性质与微观结构关系的方法。这种方法可以推广到其他软物质。
This paper investigates the strain-stress relation for the macromolecular microsphere composite (MMC) hydrogel. The novel point is to present the strain-stress model, which is based on the microscopic mixed entropy set up in the previous work and the Flory-Rehner elastic energy. Then, the numerical result of the strain-stress model is shown, which is completely consistent with the chemical experiment. Moreover, the theoretical relation of the strain-stress depends on the microscopic parameters of the MMC hydrogel. Therefore, it is a way to investigate the relation of macroscopic properties and microscopic structures of soft matters. This approach can be extended to other soft matters.
