Abstract
Nanoexpanded graphite (nEG) or graphite nanoplatelets can be used as fillers for polymer composites and nanocomposites for multifunctional applications. Composed of stacked graphene sheets, this material has an excellent potential to produce stiff nanocomposites. It also combines characteristics such as impact and thermal resistance with good electrical and thermal conductivity, abrasion or wear resistance, gas and liquid barrier properties, and low flammability. A significant advantage of using nEG as a multifunctional filler is its good balance of properties and low price compared to other similar commercially available nanofillers. This chapter discusses the main requirements for mechanical, barrier, tribological, and electrical properties, highlighting the possible synergy in some properties. Considering the processing-microstructure-properties relationships of the resulting composites and nanocomposites, this chapter also explores the application of these nanocomposites as trays for electroelectronic parts (with electrostatic discharge protection and flame retardancy), film packaging (gas barrier and UV light barrier), upcycling of multilayer packaging, and tailored wear-resistant products.
