NER: Nanoscale Composites Based on Carbon Ribbons

摘要本提案是根据NSF-0019收到的。研究计划中，苯类是一种融合环的带状分子，研究它们以前所未有的有效性增强聚合物基质的潜力。研究活动包括在选定长度的单分散群体中合成所需的菲苯，制备微观力学试验样品，并进行小规模力学试验，以证明用菲苯制成的纳米复合材料的强度和刚度明显高于用碳纳米管制成的纳米复合材料。这项研究是一项结合基础化学和材料工程的合作，目标是在基础物理科学领域接受研究生工程领域训练的本科女性。

AbstractThis proposal was received in response to NSF-0019. Research is planned in which phenacenes, which are ribbon-like molecules of fused rings, are examined for their potential to reinforce polymer matrices with unprecedented effectiveness. The research activities incl3de synthesis of the desired phenacenes in monodisperse populations of selected lengths, preparation of microscopic mechanical test specimens, and small-scale mechanical testing to demonstrate the hypothesis that the strength and stiffness of nanocomposites made with phenacenes are significantly higher than those of the corresponding nanocomposites made with carbon nanotubes. The research is a collaboration that combines fundamental chemistry with materials engineering and that targets undergraduate women being trained in the basic physical sciences for the field of post-graduate engineering.
