Research Interests:
- The Xie group aims to develop sustainable processing methods for multifunctional polymers as next-generation polymers in the health and energy industry.
- The materials of interest include electron-conducting polymers, bottlebrush polymers, branched polymers, self-assembled polymeric colloids, and associative polymers.
- The Xie group is also actively engaged in investigating the fundamental physics of polymers with unique architectures and functions by building physical models to understand their impact on chain entanglements, glass transition, crystallization, network, and liquid crystalline phase.
Research Group:
Research Methodology
- In situ rheological characterizations with optical and Raman capabilities provide unprecedented molecular-level insight into processing, thus guiding the designs of polymer structures and ink formulations.
- Advanced 3D printing methods, such as direct ink writing and electrojet writing, are developed to obtain better print quality more sustainably.
- Polymer synthesis, including ring-opening metathesis polymerization (ROMP), Grignard metathesis (GRIM) polymerization, atom-transfer radical polymerization (ATRP), are implemented to obtain the desired functional polymer structure.
Research Thrusts
- Rheology-informed advanced processing of sustainable materials
- Re-processable electrically conductive ink for 3D printing
- Novel thermophysical properties driven by unconventional chain architecture
- Functional polymer gels and networks as stretchable conductors, actuators, and sensors
