项目摘要

In this collaborative research with industry, we will create polymer blend nano composites based on polyethylene/polypropylene (PE/PP) blends with advanced nano materials such as carbon nanotubes (CNT), graphene nano ribbons (GNR) and carbon nanofiber (CNF) and nano clay. Polymer nanocomposites are materials of the future and can access property combinations previously unachievable because of exceptionally high interfacial area and similarity of filler size to the polymer molecular size. Because of this, nanocomposites are currently used in high technology applications; and the industry is predicted to be $6 Billion in size by 2018, yet there is little understanding about how materials chemistry and polymer processing influences structure and final properties of these nano composites. The aerospace and mass transit industries are keen to develop new materials based on nano materials and we propose to create new materials and develop new technologies to help them exploit this new area.** In the last decade, our group become a leading authority on electrical properties such as EMI shielding, electrical conductivity, and dielectric permittivity/loss. Hutchinson Aerospace would like to partner with us to leverage our expertise in nanomaterials, particularly, conductive nanocomposites to create new market segments for their products in areas like EMI shielding. They are experts on catalyst technology and customizing polyolefin structure. Both of the groups have significant expertise in polymer blends. The combination of our academic and their industry expertise is extremely synergistic. Researchers in the nanocomposite field typically focus on certain aspects, e.g. synthesis and characterization of nanomaterial or polymer synthesis only or processing and characterization of composite only. Though there has been excellent work performed on each, or on a couple of, the development steps, it is critical to link all the different aspects of creation of novel multiphase materials if we are to have major breakthroughs. The unique ability to perform all the steps of material development provides a significant advantage and capability to make these linkages.**************

在与行业的这项合作研究中，我们将基于聚乙二烯/聚丙烯（PE/PP）混合物与高级纳米材料（例如碳纳米管（CNT），石墨烯纳米丝带（GNR）和碳nanofiber（CNF）和Nano Clay和Nano clay和Nano Clay。聚合物纳米复合材料是未来的材料，由于界面面积异常高以及填充物与聚合物分子大小的相似性，因此可以访问以前无法实现的属性组合。因此，纳米复合材料目前用于高科技应用中。预计到2018年，该行业的规模将达到60亿美元，但对材料化学和聚合物处理如何影响这些纳米复合材料的结构和最终特性几乎没有了解。航空航天和大众运输行业热衷于根据纳米材料开发新材料，我们建议创建新材料并开发新技术，以帮助他们利用这个新区域。 Hutchinson Aerospace希望与我们合作，利用我们在纳米材料中的专业知识，尤其是导电纳米复合材料，以在EMI Shifting等领域为其产品创建新的市场细分市场。他们是催化剂技术的专家，并定制聚烯烃结构。这两个小组在聚合物混合物方面均具有重要的专业知识。我们的学术和行业专业知识的结合是非常协同的。纳米复合材料领域的研究人员通常专注于某些方面，例如仅合成和表征纳米材料或聚合物合成或复合材料的加工和表征。尽管在每种或几个开发步骤上都进行了出色的工作，但如果要具有重大突破，则将创建新颖的多相材料的所有不同方面联系起来至关重要。执行所有材料开发步骤的独特能力为建立这些联系提供了重要的优势和能力。**************************************
