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.

在这项与工业界的合作研究中，我们将创建基于聚乙烯/聚丙烯（PE/PP）与碳纳米管（CNT）、石墨烯纳米带（GNR）和碳纳米纤维（CNF）等先进纳米材料共混物的聚合物共混纳米复合材料，以及纳米粘土。聚合物纳米复合材料是未来的材料，由于极高的界面面积以及填料尺寸与聚合物分子尺寸的相似性，可以获得以前无法实现的性能组合。正因为如此，纳米复合材料目前被用于高科技应用；预计到 2018 年该行业的规模将达到 60 亿美元，但人们对材料化学和聚合物加工如何影响这些纳米复合材料的结构和最终性能知之甚少。航空航天和轨道交通行业热衷于开发基于纳米材料的新材料，我们建议创造新材料并开发新技术来帮助他们开拓这一新领域。在过去的十年中，我们的团队成为 EMI 屏蔽、电导率和介电常数/损耗等电气特性方面的领先权威。哈金森航空航天公司希望与我们合作，利用我们在纳米材料（特别是导电纳米复合材料）方面的专业知识，为其产品在 EMI 屏蔽等领域创造新的细分市场。他们是催化剂技术和定制聚烯烃结构方面的专家。两个团队都在聚合物共混物方面拥有丰富的专业知识。我们的学术和行业专业知识的结合具有极大的协同作用。纳米复合材料领域的研究人员通常关注某些方面，例如仅纳米材料或聚合物合成的合成和表征或仅复合材料的加工和表征。尽管在每个或几个开发步骤上都取得了出色的工作，但如果我们要取得重大突破，将新型多相材料创造的所有不同方面联系起来至关重要。执行材料开发所有步骤的独特能力为建立这些联系提供了显着的优势和能力。
