Abstract
Graphene is an intriguing two-dimensional carbon allotrope, heralded as promising nanoscalebrick for building macroscopic nanopapers. This chapter covers the topics of graphene production, graphene functionalization, graphene colloidal suspension, and nanomanufacturing of graphene nanopapers and their superior performance. An emphasis was placed on nanopapers based on benzenesulfonic acid functionalized graphenes. This chapter also elaborates on the breakthroughs in the development of a unique process for creating carbide-bonded graphene networks on a variety of metallic and nonmetallic surfaces. The crosslinked graphene networks with an interlayer distance of angstroms exhibit a unique combination of unprecedented properties including strong bonding, Young's modulus, and hardness higher than silicon and steel, electrical and thermal conductivities better than natural graphite, low surface friction, excellent chemical corrosion resistance and anti-abrasion, good cytocompatibility, easy micro-patterning by microfabrication techniques, and attractive semiconductive and optoelectronic characteristics. This carbide-bonded graphene coating has been successfully applied onto the Si mold for solving the challenging nonstick and thermal stress problems of precision glass optics molding.
