ULTRAFAST HEATING AND COOLING ROUTES TO NEW CARBON AND RELATED PHASE COMPOUNDS
Abstract
In this research, three specific aims will be conducted that will advance the understanding of and control over the flash Joule heating process as a rapid, energy- and water-efficient route to graphene, graphene derivatives, and hybrid carbon/inorganic materials for composites relevant to the Air Force and the nation. The first aim is to study the mechanism of the transformation of inexpensive and waste carbon, such as waste plastic and household waste, into high value 2-dimensional materials using no water and no solvents in the process. The second aim is to make 1-dimensional and 1-dimensional/2-dimensional hybrid materials. The third aim is to make hybrid organic/inorganic materials using these methods flash Joule heating methods. This has high Air Force and national relevance since it is projecting toward a new class of carbon and carbon/inorganic hybrid materials that are (a) suitable for composites with high (b) toughness, (c) thermal stability, (d) dispersibility, (e) interfacial interaction with host materials due to heteroatom insertions, and that are (e) excellent for electro/optical device construction due to the varied atomic doping with high conductivity, and (f) high surface area for air/water capture in filters. For example, these will be applied to understand the capture mechanism of “forever chemicals” such as PFAS from water sources. The syntheses described here can be done in milliseconds at low energy with no solvent or water usage, hence the methods here pave the way for future low energy consuming and non-wasteful manufacturing, a new global target for humankind.
