Možnosti využití tenziometrických metod pro charakterizaci samo-organizačních schopností polysacharidů na fázovém rozhraní

Abstract

This article describes the use of tensiometric Wilhelmi plate method for characterization of selforganization abilities of polysaccharides at the phase boundary liquid/air. Aqueous solutions of 2-hydroxyethlycellulose (2-HEC) with various polymer molecular weight and polymer concentration were studies. Results revealed that the Wilhelmi plate method is suitable for characterization of the polymeric chain flexibility and mobility at the phase boundary. Nevertheless, this method should only be considered as comparative, for it does not cover the very initial changes in process of polymer reorganization at the phase boundary.
