The main theme of this research is centered on microstructures formed in polymer systems by taking advantage of the interplay between functional groups, such as coulombic interactions. Although the studies start by using block copolymers in the absence of coulombic interactions, i.e., neutral polymers, the creation of microdomains of polymeric materials by introducing interactions, such as electrostatic charges, will be emphasized. The experiments will be complemented by a collaboration with A. Khokhlov of Moscow State University who will provide theoretical development on how clusters and aggregations which form microdomains can be calculated based on free-energy considerations. The interplay of experimental limitations and theoretical assumptions and approximations, including the use of well-defined polymer systems which are to be synthesized in collaboration with D. G. Peiffer at Exxon and the Institute of Organo-Element Compounds, Russian Academy of Sciences, Moscow, is essential to providing a deeper understanding on the formation of microstructures. The research effort is related to the exploration of our understanding on how microstructures can be manipulated in polymer systems in order to achieve specific macroscopic properties in existing polymer materials.

本研究的主题是微观结构 在聚合物体系中形成， 在官能团之间，例如库仑相互作用。 虽然研究开始时使用嵌段共聚物， 库仑相互作用，即，中性聚合物， 聚合物材料的微区通过引入相互作用， 例如静电荷。 实验 将通过与A.莫斯科洛夫 州立大学谁将提供理论发展如何 可以计算形成微畴的簇和聚集体， 基于自由能的考虑。 实验的相互作用 限制和理论假设和近似， 包括使用定义明确的聚合物系统，这些系统将被 与D. G.佩弗在埃克森和 俄罗斯科学院有机元素化合物研究所， 莫斯科，是提供一个更深入的了解， 微结构的形成。 这项研究工作与我们的探索有关。 了解如何在聚合物中操纵微结构 系统，以实现特定的宏观性能， 现有的聚合物材料。
