This Designing Materials to Revolutionize and Engineer our Future (DMREF) grant provides funding for a synergistic program of combinatorial experiments, molecular simulations, and theoretical modeling aimed at making advances in the design of pervaporation membrane materials. Pervaporation is an energy-friendly process for separation of liquid mixtures that works by preferentially transporting one of the liquid components across a selective membrane into the vapor phase on the other side. Molecular insights regarding structure-function relationships in membrane materials will be obtained by studying water-alcohol separation as the model application. The work will focus on crosslinked polyacrylate copolymer membranes that offer a high degree of tunability in chemical composition compared to traditional silicone-based membranes. High-throughput experimental screening methods consisting of matrix-based sample preparation and testing of membrane properties will be combined with molecular simulations of water and alcohol diffusion rates to quantify membrane performance. Through data-driven validation, a novel theoretical framework for membrane performance will be developed, providing predictive capabilities for rapid design of pervaporation membranes for separation applications. Pervaporation provides a cost effective alternative to the traditional energy-intensive, multi-stage distillation processes that are used for the purification of biofuels and fuel additives. This research could significantly reduce the production costs of fuels derived from renewable resources. The rapid prototyping methods to be developed will also be applicable to the design of materials for other important pervaporation applications such as desalination of water, dehydration of fuels, and removal of organics from wastewater streams. In addition to these societal benefits, the project will also have broad educational benefits through K-12 outreach activities, training of undergraduate and graduate researchers from diverse backgrounds, as well as database development for public dissemination of research findings.

这种设计材料彻底改变和设计我们的未来（DMREF）赠款，为组合实验，分子模拟和理论建模的协同计划提供了资金，旨在在泛滥膜材料设计方面提高。 Per蒸发是一种能源友好的过程，用于分离液体混合物，通过优先将一种液体成分跨越选择性膜到另一侧的蒸气相的过程。 关于膜材料中结构功能关系的分子见解将通过研究水含量分离作为模型应用来获得。 与传统的基于硅酮的膜相比，这项工作将集中于交联的聚丙烯酸酯共聚物膜，该膜具有高度可调性。 由基于基质的样品制备和膜特性测试组成的高通量实验筛选方法将与水和酒精扩散速率的分子模拟结合使用，以量化膜性能。 通过数据驱动的验证，将开发一个新型的膜性能理论框架，为分离应用的快速设计透露膜的快速设计提供了预测能力。 Per蒸发为传统的能源密集型，多阶段的蒸馏过程提供了一种经济有效的替代方法，该过程用于纯化生物燃料和燃料添加剂。这项研究可能会大大降低可再生资源衍生的燃料的生产成本。 要开发的快速原型制作方法也适用于设计其他重要的蒸发应用的材料，例如水的脱盐，燃料的脱水以及从废水流中去除有机物。 除了这些社会福利外，该项目还将通过K-12外展活动，来自不同背景的本科和研究生研究人员的培训以及数据库开发，以公开传播研究结果。
