Flory theory for polymers.
We review various simple analytical theories for homopolymers within a unified framework. The common guideline of our approach is the Flory theory, and its various avatars, with the attempt at being reasonably self-contained. We expect this review to be useful as an introduction to the topic at the graduate student level.
متن کاملFLORY THEORY REVISITED by
The Flory theory for a single polymer chain is derived as the lowest order of a cumulant expansion. In this approach, the full original Flory free energy (including the logarithmic term), is recovered. The prefactors of the elastic and repulsive energy are calculated from the microscopic parameters. The method can be applied to other types of monomer-monomer interactions, and the case of a sing...
متن کاملA suggested new nomenclature for the isomers of isocitric acid.
The destrorotatory enantiomorph of isocitric acid is found in substantial amounts in the leaves of plants of the family Crassulaceae. As a member of the Krebs tricarboxylic acid cycle, it is also presumably present, although doubtless in only trace amounts, in all living cells in which this biochemical mechanism for respiration occurs. It is, accordingly, a substance of considerable importance ...
متن کاملFlory theory for conductivity of random resistor networks
2014 We develop a Flory theory for the problem of conductivity in a d-dimensional random resistor network. We find that the conductivity exponent t is related to the fractal dimensionality df according to the Alexander-Orbach conjecture t = d 2 + df/2, where consistently with Flory theory df = (d + 2)/2 for percolation and df = 2(d + 2)/5 for lattice animals. The results are in excellent agreem...
متن کاملConformal field theory of the Flory model of polymer melting.
We study the scaling limit of a fully packed loop model in two dimensions, where the loops are endowed with a bending rigidity. The scaling limit is described by a three-parameter family of conformal field theories, which we characterize via its Coulomb-gas representation. One choice for two of the three parameters reproduces the critical line of the exactly solvable six-vertex model, while ano...
