About the Lab
Professor Han Gi Chae's research lab specializes in the development of advanced functional materials, with a focus on high-performance fibers, carbon nanotube composites, and smart textile sensors. The lab explores innovative processing techniques—such as liquid crystalline wet-spinning and 3D printing—to create materials with exceptional mechanical, electrical, and thermoelectric properties for structural and energy applications. Key research directions include the design of high-strength carbon nanotube-polymer composite fibers, multifunctional nanocomposite fibers for wearable electronics, and thermoelectric devices for waste heat recovery.

15Abstract This paper traces the historical development of high temperature resistant rigid‐rod polymers. Synthesis, fiber processing, structure, properties, and applications of poly( p ‐phenylene benzobisoxazole) (PBO) fibers have been discussed. After nearly 20 years of development in the United States and Japan, PBO fiber was commercialized with the trade name Zylon® in 1998. Properties of this fiber have been compared with the properties of poly(ethylene terephthalate) (PET), thermotropic poly
Research toward carbon nanotube fibers that are light yet extremely strong is progressing rapidly.
Textile-based sensors can perceive and respond to environmental stimuli in daily life, and hence are critical components of wearable devices.
Poly(vinylidene fluoride) (PVDF)/graphene oxide (GO) nanocomposite fibers were dry-jet wet spun at the GO concentrations of 0, 1, and 2 wt % with respect to the polymer. The as-spun fibers were drawn in the draw ratio (DR) range of 2-6.5, and the correlation between the PVDF chain conformation and the mechanical properties of the fibers upon drawing has been studied by two-dimensional correlation spectroscopy of Fourier-transformed infrared, wide-angle X-ray diffraction, differential scanning ca
Abstract Thermoelectric (TE) technologies offer promising means to enhance fossil energy efficiencies by generating electricity from waste heat from industrial or automobile exhaust gases. For these applications, thermoelectric modules should be designed from the perspective of system integration for efficient heat transfer, system simplification, and low processing cost. However, typical thermoelectric modules manufactured by traditional processes do not fulfil such requirements, especially for
