Abstract

Research on carbonaceous nanofillers such as graphene has been developing at a relentless pace as it holds the promise of creating novel materials with meliorated properties. In particular, properties of graphene have been envisaged as an ideal filler material in monolithic ceramics. This is because despite the fact that monolithic ceramics have high stiffness, strength, and stability at high temperatures, they are still susceptible to brittleness, mechanical unreliability, and poor electrical conductivity. Thanks to graphene’s exceptional properties (Young’s modulus of 1 TPa, breaking strength of 42 N/m, and in-plane electrical conductivity of 107 S/m), incorporating graphene into ceramics has great potential to produce tough and electrically conductive composites. However, due to the high surface area and exhibiting strong van der Waals forces of graphene, they have the tendency to stick together and form agglomerates. This leads to inefficient load transfer from matrix to fillers that affects properties of the resulting composite. To avert these problems, processing routes need to be modified carefully before producing graphene-based ceramic composites (GCMC). This chapter aims to report the current understanding of GCMC with two particular topics:(i) various processing routes of GCMC and (ii) application prospective of GCMC.
