ABSTRACTCTS-0304596G. Fredrickson, U of CA Santa BarbaraThis exploratory research project will assess the feasibility of conducting direct numerical simulations of nanostructure development during processing of complex fluid formulations of importance in several industries, such as paints, coatings, polymer alloys, cosmetics and processed foods. Advances in synthetic methods for producing copolymers have enabled exciting new multiphase complex fluids formulations in which the domain size falls in the nanometer range, 1-100 nm, and the geometrical arrangement of the domains can be precisely controlled by varying copolymer architecture, processing and composition variables. The framework for the simulations will be a field theoretic technique recently developed for equilibrium self-assembly and phase behavior, which will be extended to non-equilibrium systems that include couplings to stress strain and momentum density fields. The approach will be validated against experimental data on shear-induced microstructure development in poly(vinylcyclohexane)-poly(ethylene) multiblock copolymers, which have emerged as top candidates for advanced optical media resins. The project is being funded by CTS/ENG and DMR/MPS.

摘要-0304596G。加州大学圣巴巴拉分校弗雷德里克森这一探索性研究项目将评估在涂料、涂料、聚合物合金、化妆品和加工食品等多个行业中重要的复杂流体配方加工过程中对纳米结构发展进行直接数值模拟的可行性。制备共聚物的合成方法的进步使新的多相复杂流体配方成为可能，在这些配方中，相区尺寸在纳米范围内，1-100 nm，并且相区的几何排列可以通过改变共聚物的结构、加工和组成变量来精确地控制。模拟的框架将是最近发展起来的用于平衡自组装和相行为的场论技术，它将扩展到包括应力、应变和动量密度场耦合的非平衡系统。该方法将根据聚乙烯基环己烷-聚乙烯多嵌段共聚物中剪切诱导微结构发展的实验数据进行验证，这些嵌段共聚物已成为先进光学介质树脂的首选候选材料。该项目由CTS/ENG和DMR/MPS提供资金。
