Surface| Zusammenfassung: | The properties of polymer composites with graphene oxide (OG) to 15% (wt.) obtained by Hammers i Ofemana method. It is shown that the conductivity of original OG was determined by impedance spectroscopy is due primarily to the electronic component, but there is also ionic. The concentration dependence behavior of conductivity at low frequencies, as well as the real and imaginary components of the complex permittivity of 9 GHz composites varies significantly in a concentration range of 3 – 5%, due to the presence of the percolation threshold in the exhaust gas content of 4 %. |
