Necessities of Thermally Conductive Composite Materials

Rapid increase in heating by unit area due to lightweight, thin, small-size and high-integration trends in electronic goods; decrease in product life and reliability consequently

Increase in the heat-dissipation issue due to the wide spread and high output of high-voltage LED chips; 57% in life expectancy and increase in efficiency by 14% when LED temperature drops by 10°C


Small size in electric
& electronic goods
Highly functional


Fully dense parts
Highly integrated
Serious heating issue


Rising demand for polymeric
composite materials



A thin honeycomb-structured layer of 2-dimensional planar carbon atoms in SP2-hybridized configuration; as thin as 0.2nm (size of an atom) and both physically and chemically safe

Category Descriptions
Electrical Conductivity 100 times greater than copper (Cu)
Electronic Mobility 100 times greater than semiconductor silicone
