Functional Polymers and Carbons: from fundamentals to applied materials
Financial support by
Our mission is to design, create and investigate broadly defined functional polymers and carbons in a colloidal or porous form via simple chemistry and processing to confront materials challenges for a better and sustainable society. The team deals with both fundamentals in polymer science / carbon research, and the forefront challenges in materials science and engineering. Our current focus:
1. poly(ionic liquid) chemistry for better materials.
Currently, one of our focuses is the synthesis and materials application of poly(ionic liquid)s, a class of multifunctional polymers that are produced from polymerizable ionic liquids. These polymers carry a traditional profile of polymers and simultaneously maintain some distinctive properties of ionic liquids, therefore representing a new concept to build up task-specific functional polymers. Our activities on this topic cover new polymer structures and properties, the colloidal particle systems, porous polymers and their membranes, and responsive materials.
2. biopolymer-dervied functional materials
Being immersed in Stockholm University's sustainability atmosphere, our group is constantly strengthening its research activities on biopolymer-derived functional materials and devices. From nature cotton and seasand to man-made clothes and filter papers, we have introudced several new methods and concepts to produce and process materials.
3. heteroatom-doped porous carbons
Recently, our interest in polymer-derived hetero-atom-doped porous carbons with well-defined shape for energy, environment and sustainability applications grows thicker and turns into our new research strength. Their distinctive shapes includes (nano)particles, hollow nanospheres ("nanobubbles"), forms, fibers, and membranes.
Poly(ionic liquid)-derived N-doped porous carbon membranes can stabilize atomically dispersed selenium at a high content of 5.9 wt%, and serves as high-performance electrode for Hydrazine Fuel Cell. It is our collaboration work with Hong Wang at Nankai University! Angew. Chem. Int. Ed., 2019! DOI: 10.1002/ange.201907752.
Poly(ionic liquid) nanoparticles can selectively disrupt biomembranes! Our collaboration work with Rumiana and Markus at the Max Planck Institute of Colloids and Interfaces, Germany, hits Advanced Science! DOI: 10.1002/advs.201801602.
We could micropattern nanoporous poly(ionci liquid) membranes into complexed shapes! ACS Nano,2019, DOI: 10.1021/acsnano.8b07069. It comes from a joint project between MPI-CI Germany and Hongkong Polytech University. Good job, Ming-Jie, Qiang, Jushuai and Karo!
