Research Field
Cheng-Liang Liu is a Professor of Materials Science and Engineering at National Taiwan University. He received the B.S. and Ph.D. degrees in Chemical Engineering from National Taiwan University in 2002 and 2007, respectively. He then worked as visiting scientist at the University of Washington (USA) from 2005 to 2006, postdoctoral fellow at National Taiwan University from 2008 to 2010, Assistant Professor at Yamagata University (Japan) from 2010 to 2012, Assistant and Associate Professor at National Central University (Taiwan) from 2012 to 2020, before joining National Taiwan University in 2020. His research focuses on organic polymers and hybrid materials for electronic and energy applications, including transistors, memory devices, solar cells, and thermoelectric systems.
The Organic Polymer Materials and Devices (OPMD) Laboratory focuses on the research and development of organic and polymeric (opto)electronic materials and devices. Our work emphasizes a strong interdisciplinary approach, integrating chemistry, materials science, chemical engineering, and electrical engineering. The research spans the full spectrum from the molecular design and synthesis of organic/polymeric materials to the fabrication and integration of functional devices, aiming to advance next-generation soft electronic and energy-related technologies.
1. Organic Thermoelectric Materials and Devices
This research focuses on the design and optimization of organic thermoelectric systems based on conjugated polymers. Key directions include:
(1) Molecular doping of conjugated polymers to regulate charge carrier concentration, energy levels, and transport properties, thereby enhancing electrical conductivity and thermoelectric performance.
(2) Polymer-based composite thermoelectrics, integrating functional nanomaterials (e.g., carbon nanotubes and inorganic nanostructures) to synergistically improve charge transport, mechanical flexibility, and device stability.
2. Ionic Thermoelectric Systems
This research explores gel-based ion-driven thermoelectric energy conversion platforms with high Seebeck coefficients and flexibility. Major topics include:
(1) Thermogalvanic cells, utilizing redox-active electrolytes and polymer networks to achieve efficient thermal-to-electrical energy conversion.
(2) Thermally charged capacitors, focusing on ion diffusion and thermal polarization in soft materials to enable energy harvesting and storage functionalities.
