ABSTRACT
The exceptional thermal properties such as thermal conductivity, coefficient of thermal expansion, and thermal stability of graphene have been exploited to improve thermal conductivity, dimensional stability, and thermal stability of polymers for various applications. Owing to excellent electrical conductivity of graphene, it is considered as one of the most promising fillers for polymer nanocomposites for use in electronics applications. The electrical conductivity of chemically synthesized graphene is low compared to that of defects free-graphene. Excellent mechanical properties such as high elastic modulus and tensile strength of graphene sheets have attracted the attention of researchers toward polymer matrix nanocomposites. In addition to intrinsic properties, the mechanical properties of the nanocomposites are dependent on the volume fraction, size, and aspect ratio of the filler; distribution and dispersion of filler in the host matrix; and interface bonding. Graphene/carbon nanotube and graphene/polymer nanocomposites have been studied for lithium ion batteries and supercapacitor as energy storage devices.
