AI Infrastructure
AI data centers
Pulls heat away from 1,000 W+ GPUs and servers.
Green Carbon Thermal Management Platform
Green carboncools theAI era
Thermophene makes Cu-C hybrid thermal materials for AI servers, EVs and ESS. Our carbon comes from spent coffee grounds, so it costs less and emits less.

01Market Pain Points
Heat keeps rising,materials stand still
AI chips and batteries run hotter every year while carbon rules tighten. Ceramic fillers and graphite sheets alone cannot handle both.
-
01
Performance bottleneck
A single GPU now draws over 1,000 W. Conventional materials cannot remove that heat, cutting performance and lifespan.
-
02
Safety and reliability
After 30+ ESS fires in Korea, safety rules rose. Always-on data centers and EVs need materials that last.
-
03
Supply chain and ESG
80% of premium fillers are imported from Japan, the US and Germany. With EU CBAM from 2026, low-carbon materials are a must.
02Green Carbon Platform
One handful of coffee grounds,three products
Pressing yields cosmetic oil, activation yields deodorizer carbon, and the final step yields thermal filler. Nothing goes to waste.
-
STEP 1Raw material
Spent coffee grounds
200,000 tons wasted in Korea every year, with ~40% carbon yield.
-
STEP 2Defatting
Coffee oil
Sold as a cosmetic ingredient for early cash flow.
-
STEP 3Activation
Porous carbon
Sold as deodorizer feedstock. Zero loss.
-
STEP 4Core R&D
Thermal interface material
Cu-C filler with 12 W/mK, our main revenue.
- Efficiency: raw material reuse
- 100%
- Performance: revenue streams
- 3streams
- Value: coffee grounds supply (Jeonbuk, monthly)
- 1,000t
03Business
Three businesses,one cycle
Thermal materials lead. Revenue from porous carbon and cosmetic ingredients flows back into research.

04Core Technology
Four technologiesin one round particle
Pre-treatment, spray pyrolysis, reduction and nano-coating. The resulting Cu-C particle conducts heat while blocking electricity.
- STEP 01
Coffee grounds pre-treatment
Defatting and activation extract coffee oil and polyphenols and form a porous carbon precursor at near-zero raw cost.
- STEP 02
Spray pyrolysis
Ultrasonic droplets form 10 μm spherical CuO-C particles that roll like ball bearings, tackling viscosity at the source.
- STEP 03
Reduction heat treatment
Reduction at 700℃ or below builds a continuous 3D copper network for isotropic 12 W/mK.
- STEP 04
SiO₂ nano-coating
A sol-gel coating under 50 nm prevents copper oxidation and secures 10¹² Ω·cm volume resistivity.

05Comparison
Lighter than ceramic,more even than graphite
Ceramics are heavy and costly; graphite sheets conduct in one plane. Thermophene Cu-C leads evenly across six criteria.
- Thermophene Cu-C
- 28/30
- Graphite sheet
- 18/30
- Ceramic
- 13/30
