Description
Summary:Agar is a biodegradable material which can be used as counterpart of petro plastic. Also it is easily available and eco-friendly but its mechanical strength, thermal degradation, etc. are needed to be improved. In this direction, making composites of Agar with Graphene/its derivatives can be the promising approach. The credit is because of the novel features of graphene derivatives due to atomic dimension of graphene layer. As a step to achieve this objective, the composites of Agar and reduced graphene oxide (RGO) were prepared with different loading concentration of RGO (1, 1.5 and 2 wt. %) through solution casting method. Their optical and thermal behavior has been studied through UV-Visible and Thermogravemetric Analysis (TGA) respectively. With the addition of maximum 2 wt% of RGO in Agar, drastic decrease in optical transmittance of Agar has been observed. This UV blocking property of these composites can be exploited in the packaging application to prevent chemical degradation of the material caused by UV light. Also, thermal stability has been found to be increased as an effect of loading of RGO in Agar.
