Abstract
Electrical properties were studied for Pectin/PVA graphene composites films and the effect of aqueous
interaction on their properties. The conductivity and the dielectric constant of this composite are
important because Polysaccharide like pectin is increasingly being used in biomedical applications and as
nanoparticles coating materials. The Dielectric and conductivity of composite films were compared in dry
and wet condition the differences in the results were attributed to the water molecules and the hydrogen
bond which connect the three composite compounds (Pectin, PVA and Graphene) together. These
connections were allowed the hydrogen and hydroxyl group’s migrations in the composite super
molecules. On the other hand, graphene was prepared and with different techniques like Ft-IR, XRD,
SEM and AFM characterized.
