Theory of semi-dilute polymer solutions

چکیده

2014 Some properties of semi-dilute poor and good solvent polymer solutions are examined within the framework of the field-theoretic formulism. The uncontrollable polydispersivity inherent in the field-theoretic formulism is shown to produce no errors if the quantity under investigation is molecular weight independent. A renormalization group cross-over calculation correct to order 03B5 is performed to obtain an expression for the osmotic pressure which holds in both poor and good solvent limits for the special case when the ternary cluster integral vanishes.

The Shear Rheology of Semi-dilute Dna Solutions

Dilute polymer solutions and polymer melts in shear flow have been extensively studied experimentally and theoretically. However, a systematic experimental study to understand the influence of concentration, temperature and molecular weight on the rheology of semidilute polymer solutions is currently lacking. Such knowledge is of crucial importance in a number of industrial and biological conte...

The Extensional Rheology of Semi- Dilute Dna Solutions

The rheological behaviour of polymer melts and dilute polymer solutions in elongational flow have been extensively examined through experiments and theoretical predictions. However, an experimental study to understand the extensional rheological properties of polymer solutions in the semi-dilute regime is currently lacking in terms of a systematic examination of the effects of concentration and...

Non-linear dynamics of semi-dilute polydisperse polymer solutions in microfluidics: A study of a benchmark flow problem

The complex flow behaviour of semi-dilute (15 < c/c < 22.5) polydisperse polyethylene oxide (PEO) aqueous solutions flowing through a planar microfluidic geometry with an 8:1:8 contraction–expansion is systematically studied. The molecular weight and distribution of the PEO samples are analysed by Gel Permeation Chromatography (GPC). Full rheometric characterizations using various techniques in...

Scattering from solutions of star polymers

We study the scattering intensity of dilute and semi-dilute solutions of star polymers. The star conformation is described by a model introduced by Daoud and Cotton. In this model, a single star is regarded as a spherical region of a semi-dilute polymer solution with a local, position dependent screening length. For high enough concentrations, the outer sections of the arms overlap and build a ...
