Original Abstract

Hyaluronic acid is a high-molecular-weight polysaccharide found mostly in a human body and widely used in biomedical applications. Our study was focused on its electrical properties in the temperature range 25 K - 325 K and in the frequency range 100 Hz - 1 MHz. Three conductivity regions were found: DC conductivity, universal dielectric response and the super linear power law with the observed frequency dependence of conductivity being 1.06. Activation energy of the DC conductivity process was established to be 5.4 MJ/kmol. ISBN 978-4-88686-006-4
