In this program, we will create lightweight multi-functional polymer nanocomposite materials that are suitable to replace metal or highly filled composites for electronics, aerospace, automotive and military applications. These nanocomposites will be based on a hybrid design, i.e. more than one nanofiller will be used and mixed with a polymer or with a blend of polymers. By controlling the structure, we propose to localize the nanofiller and thereby reduce filler loading and conseuntly, reduce the overall weight and cost of the nanocomposite. We will use both commmercially available and custom-designed nanoparticles and fibers to yield low weight, high performance materials with unique combinations of mechanical, electrical an thermal properties. In particular, our group has the capability to make high aspect ratio metal nanowires that can be used for nancomposites with application in electronics, and these nanowires can be combined with other nanofillers or macrofillers to fill requirements for example, in the automotive, aerospace and military sectors. Polymer nanocomposites display superior properties to their microcomposite counterparts because nanofillers (1-100nm dimension) are the same size as polymer molecules and therefore, can significantly alter the physical and chemical interactions with the polymer matrix. We will take advantage of this unique nanomaterial-polymer interface and design polymer nanocomposites incorporating nanowires or combinations of nanowires and other high aspect-ratio nanofillers like inorganic clays or carbon nanotubes. These materials are the subject of intense interest because they can be manufactured using conventional polymer processing techniques and there is significant potential to commercialize these materials in a large number of high-tech applications such as photovoltaics, biomedical, packaging, sensors, catalysis, fuel cells, solar cells and others. Our goal is to produce novel multi-filler hybrid nanocomposites with multifunctional properties with a significant market potential in the electronics, aerospace, automotive and military industries.

在这个项目中，我们将创造轻质多功能聚合物纳米复合材料，适合取代金属或高度填充的复合材料，用于电子、航空航天、汽车和军事应用。这些纳米复合材料将基于混合设计，即使用多种纳米填料并与聚合物或聚合物混合物混合。通过控制结构，我们提出了纳米填料的局部化，从而减少填料的负载，从而降低纳米复合材料的整体重量和成本。我们将使用商业上可用的和定制设计的纳米颗粒和纤维来生产具有独特的机械、电气和热性能组合的低重量、高性能材料。特别是，我们的团队有能力制造高纵横比的金属纳米线，可用于电子领域的纳米复合材料，这些纳米线可以与其他纳米填料或宏填料结合，以满足汽车、航空航天和军事领域的需求。由于纳米填料（1-100nm尺寸）与聚合物分子的尺寸相同，因此可以显著改变聚合物基质与聚合物的物理和化学相互作用，聚合物纳米复合材料表现出优于微复合材料的性能。我们将利用这种独特的纳米材料-聚合物界面，设计聚合物纳米复合材料，包括纳米线或纳米线与其他高纵横比纳米填料（如无机粘土或碳纳米管）的组合。这些材料引起了人们的强烈兴趣，因为它们可以使用传统的聚合物加工技术制造，并且在大量高科技应用中，如光伏、生物医学、包装、传感器、催化、燃料电池、太阳能电池等，这些材料具有巨大的商业化潜力。我们的目标是生产具有多功能特性的新型多填料混合纳米复合材料，在电子、航空航天、汽车和军事工业中具有巨大的市场潜力。
