Lab Overview
1. Ultra-Lightweight, High-Strength Carbon Materials for Aerospace
How can a material be lighter and stronger at the same time? Building on world-leading FCCVD synthesis and scale-up technologies, we develop CNT fibers and composites that surpass carbon fiber in specific strength and copper in specific conductivity — enabling ultra-lightweight structural and EMI-shielding materials for satellites, drones, and UAM.
2. Carbon Materials for Future Energy
We develop carbon-based solutions for next-generation energy devices: carbon black interlayers and zero-swelling 3D carbon hosts that unlock anode-free all-solid-state batteries, and highly conductive, ultra-lightweight CNT wires that replace copper in electric vehicles and future mobility.
3. Carbon Materials for Semiconductor Manufacturing and Packaging
We address the material bottlenecks of the AI-era semiconductor industry with engineered carbon films: freestanding ultrathin CNT membranes for EUV pellicles (≥97% transmittance, hydrogen-plasma durability) and anisotropic heat-spreading films for HBM and advanced packaging (in-plane thermal conductivity above 500 W/mK).
4. Carbon Frontier Platform: Multiscale Integrated Design of Carbon Materials
Carbon uniquely spans diamond-level stiffness, copper-level conductivity, and 3,000 m²/g porosity within a single element. We integrate the six key industrial carbon materials into one unified research platform — built on scale-up synthesis, load transfer, percolation, and hybridization — and operate as an industry–academia–institute hub for national carbon-materials strategy.
