AbstractIn this work graphene-PVA composites samples prepared with different graphene loading (0.2, 0.5, 0.7, 1)gm, where prepared by direct mixing then dried at (60 C˚) in an oven. The present work focuses on studying the structural properties of composite, using analysis like X_ray diffraction, SEM and AFM. The results show that the chemical composition has major effect on structural properties, the phase analysis done by X_ray diffraction has confirmed the formation of the expected graphene structure where the crystal size was increased but the X-ray density was decreased when increasing the graphene content in PVA matrix. SEM shows surface image of composite films where the graphene nanoplates can be homogeneously integrated with in PVA matrix. AFM examinationshows that the surface roughness decreased with filler increasing.
