This research will focus on thermoplastic composites containing micron-sized delaminated graphite particles.Delaminated graphite has high mechanical and conductive properties. In order to impart these properties fullyto a graphite/ thermoplastic composite, it is necessary that the polymer bonds well to the graphite. Graphite hasa relatively inert surface so that conventional surface treatments do not work. New types of treatment need tobe sought. This research will seek to develop suitable surface treatments for the finely exfoliatedmicro-graphite particles, and to further investigate their potential as reinforcements in polymeric composites.The main target area for these products is thermoplastic composites which can be used to impart high strength,electrical and thermal conductivity in light-weight automotive and aerospace components. The supportingorganization is Eagle Graphite Corporation (EGC), a Canadian company that owns one of only two operatingnatural graphite mines and beneficiation plants in North America. EGC has engaged in initiatives to convert itshighly purified graphite into value-added products, while ensuring the use of environmentally friendly andsustainable processes in their operations. The knowledge generated by this project has the potential to providenew value-added products at a substantially reduced cost to various Canadian industrial sectors, including theautomotive, manufacturing and alternative energy sector.
