ABSTRACT
Graphene is a unique 2D nanostructured material with particles composed of few-nanometers thickness. This chapter highlights several graphene-based polymer nanocomposites for sensing applications, which include sensing of dopamine, glucose, ammonia, hydrazine, nitric oxide, guanine, adenine, hemoglobin, methane, and formaldehyde gas. It discusses potential applications of various graphene-based polymer nanocomposite materials, based on graphene oxide and reduced graphene oxide. Solution blending or solution mixing is the most efficient method for the production of polymer-based nanocomposites by creating a strong interface between the polymer and the filler. The melt blending or compounding technique is extensively used for the large-scale production of thermoplastic composites and nanocomposites. The in situ polymerization methodology has produced polymer composites with a covalent crosslink between the filler and the polymer matrix. Sensors can be fabricated with the combination of nanofiller and conducting polymers. As a result, graphene-functionalized or graphene-reinforced polymer nanocomposite materials can be used for various sensor applications.
