Functional Polymers and Carbons: from fundamentals to applied materials
Financial support by

Research
Our mission is to design, create and investigate broadly defined functional polymers and carbons, particularly in a well-structured (e.g., colloidal or porous) form, via simple chemistry and processing. We aim to understand fundamental knowledge and confront challenges in these materials to build up a better and more sustainable society. The team deals with both basics in polymer science and carbon research, and the forefront topics in materials science and processing to inspire new solutions to environmental and energy issues. Our current focuses are listed beneath.
1. poly(ionic liquid) chemistry for materials innovation.
Currently, one of our key focuses is the synthesis and materials application of poly(ionic liquid)s (PILs), a class of multifunctional polymers that are produced via polymerization of ionic liquids and/or attachmen of IL species covalently to the polymer chain. PILs carry a traditional profile of macromolecules and simultaneously maintain certain properties of ionic liquids, therefore representing a new concept to build up task-specific functional polyelectrolytes. Our activities on this topic cover new chemical structures. colloidal systems, porous polymers and membrane, fibers and responsive materials.
2. biomass-derived functional systems
Constructing functional systems and devices entirely or partially from renewable biomass is an important materials concept towards a sustainable society. From nature trees and cottons to clothes and filter papers, we invented new design methods and processing concepts to make better materials from renewable resources. Right now we are particularly interested in biomaterial-derived soft actuators and energy storage/conversion system.
3. Polymer-derived heteroatom-doped porous carbons for energy, sensing and catalytic application
Our interest deals with polymer-derived heteroatom-doped porous carbons with well-defined shape for energy, sensing and catalytic applications. Their distinctive shapes include (nano)particles, hollow nanospheres ("nanobubbles"), forms, fibers, and membranes. These carbons are invovled as electrode or electrocatalyst in several electrochemical processes, including batteries, supercapacitors, electrolyzers, and fuel cells.
