Flory dimension
WebThe configuration of polymers bound to a surface, whether forming a mushroom or polymer brush, is mainly dependent on the ratio between the Flory dimension (R f ) and the … WebThe Flory-Huggins interaction parameter χ gives a measure of the interaction of the polymer chains with the solvent molecules as well as the polymer-polymer interaction. To understand the meaning of χ, one must consider the free energy of mixing of pure polymer with pure solvent as considered by Flory and Huggins theory.

WebNov 12, 2013 · Flory relationship for a chain dimension provides a universal power-relationship that is a reasonable approximation to the real chains and is often used in both polymer simulations and to describe ... WebNov 12, 2013 · While the original Flory theory describes the size at a fixed temperature, as the number of monomers increases, it is possible to go beyond power laws in the current framework. The analysis allows one to discuss the temperature dependence of the size at a fixed number of monomers (assumed to be sufficiently large).
WebApr 6, 2024 · We consider a phase-field model which describes the interactions between the blood flow and the thrombus. The latter is supposed to be a viscoelastic material. The potential describing the cohesive energy of the mixture is assumed to be of Flory-Huggins type (i.e. logarithmic). This ensures the boundedness from below of the dissipation … WebOct 11, 2016 · Inside each blob, the chain undergoes a self-avoiding walk in three dimensions, with a Flory exponent of 0.6.
