Abstract:
The shaping of composites has been extensively studied for both natural fibers and graphene derivatives. The present work suggests a route for covering natural fibers through the chemical reduction, with thermal catalysis, of graphene oxide (GO). The composites were formed with different concentrations of GO to be reduced, being 0,5mg/ml, 1,0mg/ml and 1,5mg/ml, in the fabrics of sisal and jute. The samples were characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM), the latter only for the composite of concentration 1.5mg/ml. This study evaluated the adhesion of the reduced graphene oxide (RGO) coating on the sisal and jute fibers through morphological analysis, and it was observed that there was adherence and formation of composite, as was possible to observe that greater concentrations provide better surface coatings.
