摘要
碳纳米管是一种具有独特物理化学性质的新兴能源材料,其应用前景非常广阔。对此,通过分析国内外测定微米/纳米尺度下材料导热系数的先进方法———微装配装置法、3ω法及德国耐驰的LFA与瑞典hot-disk的热传递分析仪器的优劣,指出把碳纳米管制成薄膜是测量碳纳米导热系数的主要条件,说明运用分子动力学模拟法测定碳纳米管导热系数是该领域研究发展的趋势。
Carbon nanotube is one of the novel energy materials with unique physical and chemical properties.It is expected to have a wide application prospect. Thus,this paper has discussed the advantages and disadvantages of some advanced domestic and overseas methods such as microfabricated device measurements,3ωmethod,Germanic Netzsch's LFA and Swedish hot-disk thermal transfer analytic instruments,which can measure thermal conductivity of some materials in the micro-scale and the nano-scale.Also,this paper points out that one major postulate to measure thermal conductivity of carbon nanotube is to make carbon nanotube film.Meanwhile,it indicates that adopting the molecular dynamics simulation method to measure thermal conductivity of carbon nanotube will probably become the main development trend in the field.
