Chitosan (CS) is a nature polysaccharide derived the incomplete deacetylation<br />

of chitin. It has found widespread applications in sensors, electrolytes for fuel<br />

cells, flexible organic electronics, medicines, etc. For many applications it is<br />

important to have high conductivity material, but CS has low conductivity (about<br />

10 -8 S/cm). For improve conductivity of CS in the literature have been proposed<br />

to use reduce graphene oxide (rGO) which demonstrate high electronic,<br />

mechanical, and thermal properties and can be obtained graphene oxide. The<br />

graphene oxide is a well-dispersed homogeneous nanocomposites due to the<br />

large oxygen functional groups which demonstrate interaction between them<br />

and polymer matrix. In contrast rGO demonstrate bad dispersion and<br />

agglomeration. In this work homogeneous chitosan-reduce graphene oxide (CSrGO)<br />

films has been prepared by chemical reduction of graphene oxide in<br />

chitosan solution with acetic acid (CH 3 COOH) and ascorbic acid (C6H8O6)<br />

together with a heat treatment. Properties of films have been investigated using<br />

UV – Vis, XRD, Raman and dielectric spectroscopy measurements.<br />
