✦ Synopsis

The 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 a t different temperatures. The dielectric constant and the loss factor were measured a t frequencies ranging from 1 to 100 kHz a t 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 GlChialginic acid complex reported [
