24.1 Introduction
Discovery of nanoscaled carbon materials such as carbon nanotubes (CNTs),
graphite nanoplatelets (GNPs), and graphene and the development of nanocarbonbased polymer composites open new era in material science and technology
[1]. Nanoscaled carbon fillers exhibit a range of remarkable properties, such
as exceptional Young’s modulus, high tensile strength, excellent thermal and
electrical conductivity, and high surface area [2, 3]. Graphene, which consists
of several stacked graphene sheets, shows many extraordinary properties such as
high carrier mobility, mechanic stiffness, and fascinating electromagnetic response
[4, 5]. Compared with graphene, GNPs exhibit good mechanical and electrical
properties [6] and have much lower production cost and better stability. Due to
these outstanding properties, nanocarbon materials are the most promising fillers
to improve mechanical and physical properties of composites. In particular, the
incorporation of highly conductive nanocarbon particles into different polymers
(epoxy, polypropylene, poly(vinylidene fluoride), polystyrene, etc.) [6–8] allows to
create the new nanocomposites with tunable electrical properties. The most important feature of reported composites is very low percolation threshold in electrical
conductivity due to high aspect ratio of carbon nanoparticles and easy formation
of conductive network in composite. Furthermore, nanocarbon-based polymer
composites are very perspective for applications in electromagnetic shielding and
high-energy-density capacitors, owing to unique property of dramatic increase in
their dielectric constants near the percolation threshold.
