Structure versus rheological properties in fibrillar thermoreversible gels from polymers and biopolymers

摘要

This paper discusses the evolution of the elastic modulus as a function of polymer concentration in light of the molecular structure for a series of thermoreversible gels prepared from synthetic polymers and biopolymers. The gels under consideration all possess fibrillar morphology. It will be shown that Jones and Marques' theory derived for rigid networks is quite suitable for casting some light on the structure-property relation rather than the percolation approach.
