摘要:	2004年由Manchester大學的Geim和Novoselov等人，利用膠帶成功將熱解石墨分離出穩定的石墨烯。單層的石墨烯是低能隙(零能隙)半導體材料具有良好的電子遷移率 (15000 cm2/V·s)、2.3 ％光吸收、高熱導係數(5300 W/m·K)與低電阻(10-6 Ω·cm)特性，由於其獨特的結構及特性，可運用於透明導電膜、複合材料、儲氫材料、氣體感測器及強化材料等應用。常用合成方式為化學氣相沈積對SiC單晶或金屬外沿成長合成石墨烯，但需要高溫及超高真空環境，成本非常高限制商業使用的方便性和經濟價值。因此本實驗室在今年度提出了一研“分散奈米石墨烯於非晶碳基材之性能研究與應用”，其研究和應用的相關構想，計畫預計為期二年，分年敘述如下：第一年度的含奈米石墨烯非晶碳膜(a-C:nanographene)合成與分析: 利用過濾式陰極電弧電漿(FCAP)系統合成含奈米石墨烯非晶碳膜(a-C: nanographene)，並探討各種可形成觸媒之金屬鹽及氣氛源(氬氣、氫氣等)作為合成機制之研究，並探討所合成之薄膜的各種性質，如：表面形貌、機械性質、電性及光學性質。第二年含奈米石墨烯非晶碳膜(a-C:nanographene)性能與應用研究主要針對: 1、電磁遮蔽薄膜。 2、氣體感測器，特別針對臭氧感測。 3、電池的電極材料。 By repeatedly peeling highly oriented pyrolytic graphite with cellophane tape, graphene was discovered in 2004. A single sheet of grapheme is a zero-band gap semiconductor with extremely high carrier mobilities (15000 cm2/V·s) that only absorbs 2.3% of visible light. Since then graphene, a single sheet of graphite, has been explored for many practical applications including transparent conductor, composite materials, hydrogen storage , gas sensors and composite reinforcement. Graphenes have been successfully fabricated by chemical vapor deposition. The epitaxial growth of graphene layers on single-crystal silicon carbide wafers or metal under high temperature and ultrahigh-vacuum conditions. However, the combination of high cost might limit the widespread application of this approach. This proposal entitled “Studies and performances of the nanographene dispersed in amorphous carbon matrix a-C:nanographene” is a two-year project. The detailed growth mechanism are studied systematically in this proposal which may divide into the following stages in a two year program: First year:synthesis and characterization Synthesis of the a-C：nanographene film uses a process that involves a filtered cathodic arc plasma (FCAP) system. The fabrication and growth mechanism can be achieved by using a metal salt- impregnated graphite target with Ar, H2, etc. in the system. The subsequent surface morphology, mechanical, electrical and optoelectronic properties of the as-synthesized films are investigated. Second year: performances of the a-C:nanographene film, mainly focusing on hi-tech applications. 1. Electromagnetic shielding films. 2. Gas sensors, particularly on ozone-sensation. 3. Electrode carbonaceous materials for batteries.
