Optimization of the Electrical Properties of Green Synthesized Graphene/Polyester Nanocomposite

Graphene, Nanoparticles, Optimization, Rice Husk, CompositesAbstract
Graphene nanoplatelets offer exceptional properties, yet the performance and electrical conductivity of their polymer nanocomposites are often unimpressive. To overcome these obstacles, this study produced graphene from rice husk (Gr.NPs) coated with orange juice-modified green-generated silver nanoparticles (Ag.NPs)/polyester nanocomposites. The Taguchi-grey analysis was used to optimize the conductive characteristics of the developed nanocomposite. The composite's optimal performance blend was 7.5% Gr.NPs, 0.5% Ag.NPs, 100oC curing temperature, and 4ml orange juice. The remarkable electron mobility of Ag.NPs-Gr.NPs were attributed to the high electrical conductivity (2.08 x10-8 S/m), dielectric constants (5.95), and thermal conductivity (1.45 Wm-1K-1). The experimental grey relational grade of 0.615 was 95% of the way to the projected optimal grey relational grade of 0.724. This proved the sufficiency of the nanocomposite's optimal blending components for the production of electrical property furthered composites.
