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.

这项研究将重点关注含有微米级分层石墨颗粒的热塑性复合材料。分层石墨具有较高的机械和导电性能。为了充分赋予石墨/热塑性复合材料这些特性，聚合物必须与石墨良好粘合。石墨具有相对惰性的表面，因此传统的表面处理不起作用。需要寻求新型治疗方法。这项研究将寻求为精细剥离的微米石墨颗粒开发合适的表面处理方法，并进一步研究它们作为聚合物复合材料增强材料的潜力。这些产品的主要目标领域是热塑性复合材料，可用于赋予高强度、电气和性能。轻质汽车和航空航天部件的导热性。支持机构是 Eagle Graphite Corporation (EGC)，这是一家加拿大公司，拥有北美仅有的两个运营中的天然石墨矿和选矿厂之一。 EGC 致力于将其高纯度石墨转化为增值产品，同时确保在运营中使用环保和可持续的工艺。该项目产生的知识有可能以大幅降低的成本为加拿大各工业部门（包括汽车、制造业和替代能源部门）提供新的增值产品。
