（中央社記者陳至中台北26日電）成大材工系特聘教授丁志明，研發出「氣相成長碳纖維
材料」，導熱、散熱效果極佳，光靠手的溫度，就能輕易切（融化）冰塊。
成功大學今天和明安國際集團簽約，技轉金額高達新台幣8位數，預計明年底能上市。
研發該項技術的成功大學材料科學及工程系特聘教授丁志明表示，「氣相成長碳纖維材料
」的散熱效果僅次於鑽石，導熱係數是銅的5倍，密度卻不到銅的1/4，最適合用在強調輕
、薄、短、小的3C產品。
丁志明表示，碳原子以一個特殊的方式排列，散熱效果極佳，研究團隊以2、3年的時間，
讓碳纖維可以變成片狀，即可製成極好的導熱設備。
丁志明說，一片「氣相成長碳纖維材料」就像一張衛生紙一樣薄，行動設備沒有空間放風
扇，只能倚靠金屬散熱片，新的材料重量是銅片的1/8，且散熱性質更好。
明安國際董事長鄭錫坤表示，目前預估新材料的成本約是銅的2倍，但兩者單價都不貴，
應該很有市場競爭力。除了用在3C產品，未來也可能運用在其他地方，「材料做出來後，
慢慢才會發現很多運用方式」。1011026
