项目摘要

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).**

对化学和加工如何影响结构以及多相聚合物材料的最终特性几乎没有了解。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。我们将对过程基础知识进行基本和系统的研究，并找到化学处理结构 - 培训之间的联系。该研究结合了无机和有机化学，聚合物物理，过程工程和产品设计中的科学挑战，为高素质人员（HQP）编织了丰富的科学研究结构。聚合物纳米复合材料（带有纳米填料的聚合物），最后进行性质测试。我们将合成自定义纳米材料：（1）使用化学蒸气沉积（CVD）的碳纳米管（CNT）；（2）使用模板定向合成的铜纳米线（CUNW）；（3）使用溶液方法功能化的粘土和（4）石墨烯纳米纤维。纳米结构的材料特别有趣，因为它们具有极高的界面区域，并且结构特征与聚合物分子大小相当。例如，有机体修饰的纳米仪将由于特殊数量的界面面积和高模质而提供明显的机械性能增强。 CNT，石墨烯和CUNWS在非常低的负载下提高了电导率和电磁干扰（EMI）屏蔽性能。****由于这些新型的纳米材料是在实验室基准尺度上进行的，因此我们将使用我们的自定义微型融化混合器（1ML）容量（1ML）容量）来评估最佳候选者。我们将研究纳米填料修饰和聚合物官能化对电气，EMI屏蔽，电荷存储，热和机械性能的影响。通过选择正确的配方和不断变化的处理条件和方法，可以在单相材料中获得的主要属性的关键组合。****多相聚合物材料具有在大量应用中进行商业化的巨大潜力，例如电子，光伏，生物医学，包装，包装，包装，自动化，汽车，空间，催化细胞，燃料和燃料细胞，燃料和其他工业，其他工业，其他工业。通过此计划，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。这项研究将为这一领域增加关键结果，并将在该计划中对九（9）个材料化学家，聚合物科学家和工程师组成的多学科团队进行培训（HQP：2 PhD：2 PhD，1 MSC，2个博士后研究员和4名本科生。** ** **。
