Abstract
In this talk, I will first present our recent work on linker-mediated vitrimers[Science, 2017, 356, 62], for which we formulate a mean field theoretical framework to explain the reentrant gel-sol transition observed in experiments[Macromolecules, 2020, 53, 1180; Proc. Natl Acad. Sci. USA, 2020, 117, 27111]. Afterwards, based on the theoretical framework, I will talk about a new design of vitrimers, which can be a liquid at low temperature and solidify to be a crosslinked elastomer at higher temperature with possible applications as injectable implants [JACS Au, 2022, 2, 2359].
Biography
Dr.Ni is an associate professor in the School of Chemistry, Chemical Engineering and Biotechnology in Nanyang Technological University, Singapore. He received his Ph.D of Physics in 2012 from Utrecht University (the Netherlands) working with Prof. Marjolein Dijkstra focusing on the computational study on the self-assembly of colloidal systems. From 2012 to 2014, he did his postdoc with Profs. Martien A. Cohen Stuart and Peter G. Bolhuis focusing on the self-assembly of fibril-forming polypeptides. In 2014, he was awarded the NWO VENI fellowship which is the most prestigious personal grant for young scientists in the Netherlands to start independent research lines. In 2016, he was awarded the Best Research Prize by the European Cooperation in Science and Technology (COST) Action – Flowing Matter [An annual prize for European Early Stage Researchers in soft matter within eight years after the date of PhD]. His research has been published in a number of top scientific journals, e.g. Nature, Nature Communications, Science Advances, PNAS, PRL, etc.
