WebJan 1, 2005 · Flory exponent. I G (0): zero angle scattered intensity for solid-like scattering. I L (0): zero angle scattered intensity for solution-like scattering. Ξ: characteristic length for solid-like non-uniformity. R g: radius of gyration of solid-like non-uniformity. κ −1: Debye length. S(x): structure factor. x: reduced scattering vector. r 0: The statistics of a single polymer chain depends upon the solubility of the polymer in the solvent. For a solvent in which the polymer is very soluble (a "good" solvent), the chain is more expanded, while for a solvent in which the polymer is insoluble or barely soluble (a "bad" solvent), the chain segments stay close to each other. In the limit of a very bad solvent the polymer chain merely collapses to form a hard sphere, while in a good solvent the chain swells in order to maximize th…

WebWe found an exact expression for the Flory radius R (F) of Gaussian polymers placed in an external periodic field. This solution is expressed in terms of the two parameters eta and a that describe the reduced strength of an external field and the period of the field to the polymer gyration radius ratio, respectively. WebThe Flory radius, R F, is defined by the random walk law, The Flory radius applies, for the most part, in the melt. When a polymer is put in solution with an organic solvent, such as … WebAll flosses are packaged in 100% plastic-free packaging.
