项目摘要

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.

这项研究将重点放在含有微米大小的分层石墨颗粒的热塑性复合材料上。塑料石墨具有高机械和导电性能。为了使这些特性完全赋予石墨/热塑性复合材料，必须使聚合物与石墨良好键合。石墨哈萨相对惰性表面，因此常规的表面处理不起作用。新型治疗需要寻求。这项研究将旨在为细化的微透明岩颗粒开发合适的表面处理，并进一步研究其作为聚合物复合材料增强的潜力。这些产品的主要目标是热塑性复合材料，可用于散发高强度，轻型自动化自动化自动化自动化自动化和气体空间组合物的电导率。辅助组织是一家加拿大公司Eagle Graphite Corporation（EGC），该公司在北美拥有仅有的两个运营自然石墨矿和慈善工厂之一。 EGC已发挥了将其纯化的石墨转换为增值产品的举措，同时确保在其运营中使用环保和可维护的流程。该项目产生的知识有可能以大幅降低的加拿大工业领域的成本降低了增值产品，包括theautomotive，制造业和替代能源领域。
