Strain-stress relation in macromolecular microsphere composite hydrogel

doi:10.1007/s10483-016-2110-9

Abstract

Abstract:

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.

Key words: free energy functional, microscopic parameter, strain-stress model, large deformation
