Abstract

In this paper, starch nanocomposite are synthesized by the addition of nanocrystalline montmorillonite and graphite and identified by various characterization methods. To improve the nanocomposite properties of starch, it is activated using methyl methamethacrylate monomer, and then polymer (methyl methacrylate) polymer is placed on the starch by polymerization reaction on starch. Methylene base-acrylamide mesh agent has been used to make cross-links in polymers and to cross-link them. The composite prepared in this study was identified by various methods, including nuclear magnetic resonance imaging, subcutaneous radiography, scanning electron microscopy imaging, and heat weight analysis. Graphite has been used as a conductive additive in composites and the electrical conductivity of composites has been evaluated by the spectroscopic method of electrochemical impedance. Different amounts of graphite, including 0, 5, 10 and 15% by weight of graphite, were used as additives in the composite, and an electrical conductivity study showed that a composite containing 10% by weight of graphite showed the highest conductivity. The results showed that the starch composite of the grid containing the monoclonal nanofluid additives and graphite had an electrical conductivity.
