研究主要分为以下三个方向：
方向一
| MOF - Polymer Interfaces |
Porosity is a material property closely associated with rigidity. Processability, however, is strongly related to ductility and flexibility. Benefiting from the rigid molecular construct through strong coordination bonds, most metal-organic frameworks (MOFs) gain their permanent porosity at the cost of material flexibility and processsability. On the other hand, many polymers inherit excellent processability at the cost of porosity. Combining MOFs and polymers is a promising way to bring these two contradictory properties together. This part of our research focuses on bridging the interface between MOFs and polymers. By doing so, we aim to 1) understand the fundamental aspects of MOF-polymer interfaces; 2) engineer composite materials interfaces to maximize material properties and 3) create well-defined hierarchical MOF-polymer composite materials with unique properties for energy and environmental related applications. | |
方向二
| Hierarchical Porous Composites |
The physical and chemical properties of a porous material are encoded not only at the molecular scale (atomic or molecular assembly) but also at the mesoscale. Hierarchical arrangement of porous materials at the mesoscale can often lead to the emergence of unexpected properties specific to such architecture. The extreme diversity of metal-organic framework (MOF) and covalent-organic framework (COF) structures rooted in the endless combinations between organic linkers and metal building units. Nevertheless, for a given application, it is still challenging to find a MOF that meets all the requirements. By arranging different MOFs at a specific mesoscopic hierarchical order, it is possible to combine their merits that are usually contradictory to each other. This part of research focuses on the fundamental understanding of the interfaces between MOFs and COFs. Meanwhile, we aim to develop new strategies to construct hierarchical MOF/COF composites and pursue their unique properties thereafter. | |
方向三
| Gas Separation Membranes |
Natural gas sweetening, H2/N2 separation, and olefin/parafin separation are some of the most energy intensive gas separation processes in industry. Practicing other separation such as CO2 removal from flue gas and direct air capture of CO2 may have a direct impact on mitigating global warming. Compared to traditional separation technologies (e.g. cryogenic distillation and wet scrubbing), membrane gas separation using composite materials is an attractive alternative to considerably lower the energy consumption of these processes. The idea of compositing rigid crystalline porous fillers with soft polymeric matrix creates new possibilities to continuously improve membrane performance. However, the addition of a new phase also generates new problems including non-ideal filler distribution, interfacial compatibility and reduced mechanical properties, which complicate the rational design of materials. We are interested in constructing well-defined composite membranes using various synthetic tools to simplify these problems and then subsequently find their structure-property correlations. |
Research Summary
Our research interests focus on rational design, synthesis and fabrication of porous composite materials with hierarchy across different length scales. We strive to understand the physical and chemical properties of materials interfaces. By combining such knowledge with a library of synthetic tools from inorganic, organic and polymer chemistry, we aim to construct well-defined porous composite materials with desired atomic, mesoscopic and even macroscopic ordering which will subsequently aid us to decipher the structure-property relationship of these complex systems.
