There is little understanding about how chemistry and processing influences structure and the consequent final properties of multiphase polymer materials. Therefore, we will investigate all steps of the design and development of multiphase polymer materials, and understand the interrelations between the different steps. We will perform a fundamental and systematic study of process fundamentals, and find links between chemistry-processing-structure-properties. The research combines scientific challenges in inorganic and organic chemistry, polymer physics, process engineering and product design, weaving a rich fabric of scientific investigation for highly qualified personnel (HQP).****We will start with synthesis of novel nanomaterials and specialty polymers, and then we will use polymer processing methods to create multi-component polymer blends (mixtures of two or more polymers) and polymer nanocomposites (polymers with nanofillers), and finally, perform property testing. We will synthesize custom nanomaterials: (1) Carbon nanotubes (CNTs) with and without doping using Chemical Vapor Deposition (CVD); (2) Copper nanowires (CuNW) using template-directed synthesis; (3) functionalized clays and (4) graphene nanoribbons using solution methods. Nano-structured materials are especially interesting since they have exceptionally high interfacial area and the structural features are comparable to the polymer molecular size. For example, organo-modified nanoclays would offer significant mechanical property enhancement due to the extraordinary amount of interfacial area and the high modulus of clay. CNTs, graphene and CuNWs enhance electrical conductivity and electromagnetic interference (EMI) shielding properties at very low loadings.****Since these novel nanomaterials are made on lab bench scale, we will use our custom miniature melt mixer (1mL capacity) to evaluate the best candidates. We will investigate the effect of nanofiller modification and polymer functionalization on, and the consequent improvement in electrical, EMI shielding, charge storage, thermal and mechanical properties. Key combinations of properties not available in single-phase materials are possible by choosing the right formulation and changing processing conditions and methods.****Multiphase polymer materials have significant potential to be commercialized in a large number of applications such as in electronics, photovoltaics, biomedical, packaging, automotive, aerospace, catalysis, fuel cells, solar cells and other industries. Through this program, we will provide guidance and insight to manufacturers and users of multiphase polymer materials. This research will add key results to this field, and a multidisciplinary team of nine (9) material chemists, polymer scientists and engineers will be trained in this program (HQP: 2 PhD, 1 MSc, 2 Post-doctoral fellows and 4 undergraduates).**

人们对化学和加工如何影响多相聚合物材料的结构和最终性能知之甚少，因此，我们将研究多相聚合物材料的设计和开发的所有步骤，并了解不同步骤之间的相互关系。该研究结合了无机和有机化学、聚合物物理、工艺工程和产品设计方面的科学挑战，为高度的科学研究编织了丰富的内容。合格人员（HQP）。****我们将从新型纳米材料和特种聚合物的合成开始，然后我们将使用聚合物加工方法来创建多组分聚合物共混物（两种或多种聚合物的混合物）和聚合物纳米复合材料（具有纳米填料的聚合物） ），最后，我们将合成定制纳米材料：（1）使用化学气相沉积（CVD）掺杂和未掺杂的碳纳米管（CNT）；使用模板定向合成的纳米线（CuNW）；（3）功能化粘土和（4）使用溶液方法的石墨烯纳米带纳米结构​​材料特别有趣，因为它们具有极高的界面面积并且结构特征与聚合物分子尺寸相当。例如，由于碳纳米管、石墨烯和铜纳米线具有巨大的界面面积和高模量，有机改性纳米粘土将显着提高机械性能。以及在极低负载下的电磁干扰 (EMI) 屏蔽性能。****由于这些新型纳米材料是在实验室规模上制造的，我们将使用我们的定制微型熔体混合器（1mL 容量）来评估最佳候选材料。通过选择正确的配方和改变加工条件，纳米填料改性和聚合物功能化对电气、EMI 屏蔽、电荷存储、热和机械性能的影响以及随之而来的改善是可能的。方法。****通过该计划，多相聚合物材料在电子、光伏、生物医学、包装、汽车、航空航天、催化、燃料电池、太阳能电池和其他行业等大量应用中具有巨大的商业化潜力。 ，我们将为多相聚合物材料的制造商和用户提供指导和见解，这项研究将为该领域增添关键成果，并且由九 (9) 名材料化学家、聚合物科学家和工程师组成的多学科团队将在该计划 (HQP) 中接受培训。 ：博士 2 名、硕士 1 名、博士后 2 名、本科生 4 名）。**
