Summary:Eumelanin is a perspective conductive biomolecular material, which has already been used for making various bioelectronic devices ranging from transistors to batteries. It is known that its conductivity mechanisms are governed by a redox comproportionation reaction. However, most studies devoted to the redox chemistry of eumelanin lack the data on the temperature behavior of its properties. We use broadband dielectric spectroscopy and heat capacity measurements to study the influence of hydration and temperature on eumelanin's conductivity.
