Structure of vapor grown carbon fiber mat (VGCF) gives rise to excellent mechanical properties, very high electrical and thermal conductivity. A National Cheng Kung University (NCKU) research team has developed a VGCF mat which exhibits ultra-high thermal conductivity, an ideal heat spreader material for potential use in electronic devices such as smart phones and tablet computers.
“The finding not only marks a milestone in electronic production, but also raises the visibility of Taiwan’s academic research,” Hwung-Hweng Hwung, president at NCKU and a renowned hydraulic expert who hailed the groundbreaking innovation of VGCF mat, said in a statement.
The technology has attracted attention from industry executives and AD Group, a Taiwan-based golf manufacturing company, who signed a technology licensing agreement with NCKU and launched a new business unit to commercialize the product. The technology transfer contract signing ceremony was held with representatives of both side, Director Mi-Ching Tsai, NCKU Research and Services Headquarters (RSH), and Bernard Cheng, the Chairman of the AD Group.
Jyh-Ming Ting, the Chairman of the Department of Materials Science and Engineering, pointed out that the material with VGCF has an outstanding thermal conductivity of 1950 W/m-K which is five times that of copper and will be the most preferable cooling material for mobile devices.
The theory behind the production of VGCF is simple but the technical threshold is rather high, according to Ting’s research team which is capable of carrying out the mass production of the material. VGCF mats are suitable for high-functioning and thin electronic products which may include flat-screen TV and laptop computers, according to Ting, adding that high-density LED, Li-ion battery module are also possible applications of the material.
According to the result of Industry-Academia Collaboration Performance Evaluation, initiated by the Ministry of Education in 2009, NCKU has won the 1st Place in 4 consecutive years under different categories, added Director Tsai.
