WebDec 22, 2004 · Flory and J. Rehner, Jr., J. Chem. Phys. 12, 412 (1944). The influence of a generalized homogeneous strain of any type on swelling has been treated recently by Treloar, “Royal Society discussion on Physical and Chemical Properties of Hydrocarbon Gels,” (in press). WebJan 20, 2024 · The results, from the swelling experiments, exploiting Flory-Rehner theory, and rheology, strongly showed a cross-linker content-dependent behavior. The study of cross-linking density allowed to shed light on the efficiency of the synthesis reaction methods. Overall, our study demonstrates that by varying the amount of cross-linking …

WebIn this paper, we explain the increased swelling of crosslinked polysaccharide microgels by the increase of sugar concentration using a modified Flory–Rehner theory. This theory is validated via the investigation of the swelling of dextran microgels in sugar solutions, which can be viewed as a model system for crosslinked starch in sugar ... WebThe Flory-Rehner equation (2,13) was used to interpret the swelling of the polyurethane networks in pure dioxane in order to calculate, the molecular weight between crosslinks.
