  • 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 sigma ~ omega1.06. Activation energy of the DC conductivity process was established to be 5.4 MJ/kmol.
