| description | The temperature-frequency dependences of the electrical conductivity for biocomposite formed systems are obtained, and the influence of the carbon temperature type on the changes of the electrically conductive systems is observed. It has been established that the electrical conductivity at a direct current of 1.2 Ohm-1 • m-1 is formed for CNT/aspartate biocomposites. Such electrical conductivity is weakly dependent on frequency. The temperature dependence of the conductivity of CNT/aspartate allowed to set the activation energy at the level of Eg=0,037 eV, which indicates the predominant role of the mechanism of translucency. For biocomposites, TEG / aspartate obtained by ultrasonic dispersion of components in an aqueous medium, the nature of the frequency dependences of the electrical conductivity reflects the combination of the inputs in the material of two component components with different types of mechanisms. Namely: electronic for the carbon temperature and semiconductor for the organic component. This type of dependence at lower temperatures is due to the desorption of water molecules from the surface, through which the charge is transferred by the migration of the proton to the hydroxyl groups. The next increase in temperature causes the activation of electrons and their contribution to the electrical conductivity of the biocomposite. For the TEG / aspartate biocomposite, the calculated value of activation energy will be 0.170 eV. |
