项目摘要

PART 1. NON-TECHNICAL SUMMARYThis project will consider a class of complex molecularly branched ionic polymers with various chemical compositions, morphologies and tunable physical properties in order to understand composition-structure-property relationships and enhance ion-group mobility. These novel ion-containing polymeric materials will be synthesized to contain a high concentration of well-ordered charged groups. They will be processed into continuous morphologies and investigated by various advanced techniques. This approach will provide an organized material platform with potentially high and controlled ionic transport, as well as liquid electrolytes with low temperature and mechanical stability. Such organized multi-functional polymeric materials with controlled continuous morphologies are important for prospective novel solid polyelectrolyte media. These could offer potential for new lightweight, robust, temperature-stable, and safe batteries to replace current liquid-based batteries. This research will be integrated with a multifaceted educational program for graduate and undergraduate students, as well as outreach to high school students and the general public to cultivate their interest in nanomaterials and more broadly STEM careers. PART 2. TECHNICAL SUMMARYThis project will consider newly synthesized branched poly(ionic liquid)s with different functional cores, ion species, and degrees of ionization. The PI's group will explore different chemical architectures to promote various micellar morphologies and their assembly into continuous percolated networks across multiple spatial scales starting from individual macromolecules and extending to the formation of long-range interconnected anisotropic core-shell morphologies. The project is focused on understanding the role of highly asymmetric compositions of new multicomponent branched ion-containing polymers. These will be tailored to yield continuous domain morphologies via emergence of long-range and network organization such as expanded interconnected cylindrical and nanotubular micelles. The general hypothesis of the proposed research is that branched macromolecular architectures with multiple functionalities can be leveraged to mediate the organization of poly(ionic liquid)s and guide their assembly into predictable, percolated morphologies of interconnected domains that are distinct from those normally encountered in discrete nanostructures. The experimental plan will enable a systematic and predictive understanding of component-structure-property relationships for these complex materials. .This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

第1部分。非技术摘要项目将考虑一类复杂的分子分支离子聚合物，具有各种化学成分，形态和可调的物理特性，以了解组成结构 - 结构 - 特性关系并增强离子组的迁移率。这些新型含离子的聚合物材料将被合成，其中包含高液序的充电组。它们将被处理成连续的形态，并通过各种高级技术进行研究。这种方法将提供一个有组织的材料平台，具有潜在的高和受控的离子传输，以及低温和机械稳定性的液体电解质。具有控制连续形态的有组织的多功能聚合物材料对于前瞻性新型固体聚电解质培养基很重要。这些可能为新的轻巧，健壮，温度稳定和安全的电池提供潜力，以取代当前的液体电池。这项研究将与一项针对研究生和本科生的多方面教育计划以及与高中生和公众的宣传，以培养他们对纳米材料的兴趣，并更广泛地促进职业。第2部分。技术摘要项目将考虑具有不同功能核，离子物种和电离程度的新合成的分支聚（离子液体）。 PI的小组将探索不同的化学体系结构，以促进各种胶束形态及其组装，以从单个大分子开始，并扩展到远距离互连的各向异性方向异性核心 - 核心壳形成。该项目的重点是理解新的多组分分支离子聚合物的高度不对称组成的作用。这些将根据远程和网络组织的出现（例如扩展的互连圆柱形和纳米管胶束）的出现来量身定制，以产生连续的域形态。提出的研究的一般假设是，可以利用具有多种功能的分支大分子结构来介导聚（离子液体）S的组织，并将其组装成可预测的，可预测的，相互连接的域的可预测的形态，这些形态与在离散的纳米构造中正常遇到的互连域不同。实验计划将使对这些复杂材料的组件结构 - 特制关系有系统的预测理解。该奖项反映了NSF的法定任务，并通过使用基金会的智力优点和更广泛的影响审查标准来评估值得支持。
