Ryan Sayko, Michael Jacobs, and Andrey V. Dobrynin Knowledge of the interaction parameters for polymers in different solvents is crucial for exploring the viscoelastic properties and processing capabilities of polymer solutions. Here, we apply a scaling theory of semidilute polymer solutions … Read more

Ryan Sayko, Michael Jacobs, and Andrey V. Dobrynin We apply a scaling theory of semidilute polymer solutions to quantify solution properties of polysaccharides such as galactomannan, chitosan, sodium carboxymethyl cellulose, hydroxypropyl methyl cellulose, methyl cellulose, xanthan, apple pectin, cellulose tris(phenyl … Read more

Michael Jacobs, Carlos G. Lopez, and Andrey V. Dobrynin We implemented a scaling approach, based on the relationship between the solution correlation length ξ = lgν/B and the number of repeat units per correlation blob g for polymers with repeat … Read more

Andrey V. Dobrynin, Michael Jacobs, and Ryan Sayko Knowledge of interaction parameters and Kuhn length for a polymer/solvent pair is a foundation of polymer physics of synthetic and biological macromolecules. Here, we demonstrate how to obtain these parameters from the … Read more

Andrey V. Dobrynin and Michael Jacobs Entanglements in polyelectrolyte solutions are a controversial issue in polymer science. Experimental studies during the last 20 years have raised doubts about the applicability of the concept of entanglements developed for neutral polymers to … Read more
