By Kishor Kumar Sadasivuni, Deepalekshmi Ponnamma, Jaehwan Kim, Sabu Thomas

This publication covers graphene strengthened polymers, that are worthy in digital functions, together with electrically conductive thermoplastics composites, thermosets and elastomers. It systematically introduces the reader to primary elements and leads over to real purposes, akin to sensor fabrication, electromagnetic interference defensive, optoelectronics, superconductivity, or reminiscence chips. The ebook additionally describes dielectric and thermal behaviour of graphene polymer composites - homes that are necessary to think of for the fabrication and construction of those new digital fabrics. The contributions during this publication significantly speak about the particular questions within the improvement and functions of graphene polymer composites. it's going to hence attract chemists, physicists, fabrics scientists in addition to nano technologists, who're drawn to the homes of graphene polymer composites.

The two additional peaks at 1,037 and 1,088 cm−1 for MG and at 1,044 cm−1 for PMG corresponds to distinct C–O stretching vibrations, involving the formation of metal nanoparticles by binding C–O with different metal ions [31]. In general RGO, the intensity of the O–H band at 3,430 cm−1 was reduced due to the de-oxygenation of the GO functionalities. For the RGO-(PMMA) nanocomposites obtained from the in situ method, the bands present at 3,420, 1,726 and 1,620 cm−1 are due to the presence of O–H, C = O and C = C groups, respectively [33].

A brief description about the synthesis and ­characterization of graphene is also included in this chapter. Since the present book deals with the applications of graphene nanocomposites in various fields of flexible and wearable electronics, we think this chapter is of much significance as electrical conductivity is the basis for graphene’s such applications. After giving an outline about the electrical properties of graphene polymer composites, the various factors affecting the conductivity such as filler aspect ratio, dispersion, modification of graphene surfaces etc.
