Journal ArticleDOI
Structure of sodium carboxymethyl cellulose aqueous solutions: A SANS and rheology study
TL;DR: Viscosity measurements are found to be in qualitative agreement with scaling theory predictions for flexible polyelectrolytes exhibiting semidilute unentangled and entangled regimes, followed by what appears to be a crossover to neutral polymer concentration dependence of viscosity at high concentrations.
Journal ArticleDOI
Does Flory-Rehner theory quantitatively describe the swelling of thermoresponsive microgels?
TL;DR: A comparison of the χ parameter obtained from FR theory with values for the linear polymer reveals that the agreement between experiment and theory is somewhat fortuitous, and although the FR model can accurately describe experimental data, the accuracy of the obtained fit parameters is significantly poorer.
Journal ArticleDOI
Viscosity and Scaling of Semiflexible Polyelectrolyte NaCMC in Aqueous Salt Solutions
TL;DR: In this paper, the authors investigate the viscosity dependence on concentration and molecular weight of semi-lexible polyelectrolyte sodium carboxymethylcellulose (NaCMC) in aqueous salt-free and NaCl solutions.
Journal ArticleDOI
Electrostatic and Hydrophobic Interactions in NaCMC Aqueous Solutions: Effect of Degree of Substitution
TL;DR: The rheology of water-soluble polyelectrolytes at intermediate and high concentrations is controlled by entanglement, hydrophobic, and electrostatic interactions, whose influences are difficult to isolate as discussed by the authors.
Journal Article
Electrostatic and hydrophobic interactions in NaCMC aqueous solutions: effect of degree of substitution and solvent medium on structure and rheology.
TL;DR: The rheology of water-soluble polyelectrolytes at intermediate and high concentrations is controlled by entanglement, hydrophobic, and electrostatic interactions, whose influences are difficult to isolate.
