Polymer composite membranes containing nanostructured fillers have many potential applications in industrial sectors. For example, in emergent technologies ranging from carbon dioxide capture and sequestration to hydrogen purification, and for use in water desalination and vapor recovery systems, as well as in medical devices and smart sensors. Next-generation mixed-matrix membranes (MMMs) which incorporate porous metal-organic frameworks (MOFs), offer the unique opportunity for combining high selectivity and chemical tuneability of MOFs with the ease of processing and robustness intrinsic to conventional polymers. While the development of such MOF-polymer mixed-matrix membranes is in its infancy, there are already archetypal composite systems recently discovered that demonstrate substantial improvement in its functional performance (particularly gas/liquid permeability and selectivity properties). Much progress has been accomplished in this rapidly growing area. However, many important questions remain to be answered about its core mechanical-thermal properties and long-term chemical stability; its structure-function mechanical correlation information is scarce and, hitherto membrane structural integrity (under static or dynamic loading) is not well understood. This project will address the aforementioned problems, establishing an accurate knowledge of the underpinning physical properties, and pinpointing microscopic mechanisms that control the structural and functional performance of novel membranes. This research will yield systematic structure-function relationships, formulate innovative methodologies and detailed material model descriptions, which will enable prediction, rational design and engineering of new membranes. Resilient composite membranes featuring an improved damage tolerance coupled with optimal functionalities will enable many energy, environmental and multifunctional technologies benefitting the wider public.

含有纳米填料的聚合物复合膜在工业领域有许多潜在的应用。例如，在从二氧化碳捕获和封存到氢气净化的新兴技术中，以及用于海水淡化和蒸汽回收系统，以及在医疗设备和智能传感器中使用。下一代混合基质膜(MMM)结合了多孔金属-有机骨架(MOF)，为将MOF的高选择性和化学可调整性与传统聚合物固有的易于加工和坚固耐用相结合提供了独特的机会。虽然这种MOF-聚合物混合基质膜的开发还处于起步阶段，但最近已经发现了一些原型复合体系，它们在功能性能(特别是气液渗透和选择性性能)方面表现出了显著的改善。在这一快速增长的领域已经取得了很大进展。然而，关于其核心力学-热学性质和长期化学稳定性的许多重要问题仍有待回答；其结构-功能力学关联信息很少，并且到目前为止，膜的结构完整性(在静态或动态载荷下)还没有被很好地理解。该项目将解决上述问题，建立支撑物理性质的准确知识，并精确定位控制新型膜结构和功能性能的微观机制。这项研究将产生系统的结构-功能关系，制定创新的方法和详细的材料模型描述，这将使新膜的预测、合理设计和工程实现成为可能。具有更好的损伤容忍度和最佳功能的弹性复合膜将使许多能源、环境和多功能技术造福于更广泛的公众。
