Abstract: This talk will focus on a special class of functional polymers, made up from polymerization of ionic liquids (ILs). They are commonly termed poly(ionic liquid)s or polymerized ionic liquids (PILs). In such a structure configuration, some unique properties of ILs are incorporated into the macromolecular architecture. This innovation in structure design in turn expands the property window and application spectrum of ILs and traditional polyelectrolytes. The first part of my talk deals with PIL colloidal nanoparticles that were synthesized via dispersion polymerization of vinylimidazolium-type ionic liquid monomers with long alkyl chains. The second part of my talk will discuss porous polymer membranes. Functional porous polymer membranes with large surface area can be applied in broad fields, including catalysis, separation, filtration and energy applications. Biosketch： Dr. Jiayin Yuan studied chemistry at the Shanghai Jiao Tong University. After moving to Germany he went first to the University of Siegen before he then moved to the University of Bayreuth. There Yuan received his PhD (Summa cum laude) supervised by Axel H. E. Müller in 2009. After postdoctoral work with Markus Antonietti at the Max Planck Institute of Colloids and Interfaces in Potsdam-Golm, he started his independent career in 2011. Since then he is leading a research group in the department of Colloid Chemistry. In 2014, he received one of the ERC Starting Grants. Endowed with up to 1.5 Mio EUR this grant promotes basic research on nanoporous polymer membranes in the next five years. He received the Otto-Warburg Award in 2009, Dr. Hermann-Schnell Award in 2015 and Dozentenpreis (Young Investigator Award) in 2016.
