Manufacturing and characterization of multifunctional polymer-reduced graphene oxide nanocomposites

In this chapter, multifunctional nanocomposite films using reduced graphene oxide and poly(methyl methacrylate) were produced using electrospinning and compression molding techniques. Electrical conductivity and gas-barrier properties of the composite films were investigated experimentally using the four-probe method and oxygen permeability testing as per ASTM Standard D3985-02, respectively. Based on the experimental results, the films are highly suitable for applications in food and beverage packaging and chemical-processing plants. The analytical model outcomes for EMI-shielding effectiveness were positive, and the theoretical cases suggest increased shielding efficiency values with increase in the number of layers in the film.
