Abstract

AbstractThe dielectric properties, DC electrical conductivity, and I‐V characteristics of thin films of polyelectrolyte complexes formed by glycol chitosan (GlChi) with mucopolysaccharides chondroitin sulfate A (CSA), chondroitin sulfate C (CSC), and hyaluronic acid (HA) have been studied at different temperatures. The dielectric constant and the loss factor were measured at frequencies ranging from 1 to 100 kHz at all temperatures. The behavior of GlChi–CSA and GlChi–CSC complexes resembles that of the GlChi–dextran sulfate complex reported earlier. The GlChi–HA complex behaves differently and is similar to the GlChi–alginic acid complex reported [Srinivasan, R. & Kamalam, R. (1982) Biopolymers 21, 251–263, 265–275].
