Use of micron-sized exfoliated graphite as reinforcing filler to enhance the mechanical, thermal and electrostatic dissipative capacity properties of polypropylene composites

本研究主要针对含有微米级石墨层片的热塑性复合材料，石墨层片具有良好的力学性能和导电性能。为了赋予石墨/热塑性复合材料充分的这些性能，聚合物必须与石墨良好地结合。石墨是一种相对惰性的表面，因此常规的表面处理不起作用。需要寻求新的治疗方法。本研究将寻求开发合适的表面处理的细剥离的微石墨颗粒，并进一步研究其作为增强聚合物复合材料的潜力，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，导电性和导热性的轻质汽车和航空航天部件。支持组织是鹰石墨公司（EGC），一家加拿大公司，拥有北美仅有的两个运营天然石墨矿和精炼厂之一。EGC致力于将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。

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.
