碳材料的导热性能测试 (Thermal Conductive Properties of Carbon Materials)

Chinese Language
10:00 – 11:00 AM CST

“碳”是神奇的多元的,它既是最硬又是最软的材料,既是绝缘体又是导电体,既是隔热材料又是导热材料。碳材料低调的服务于生活的方方面面,从最贴近我们的生活领域,到科技前沿的航空航天;从人类的生存中作为热能来源的木炭,到表达爱意浓浓的炫亮钻石;从开启人类文明用来书写的墨汁,到远征宇宙的碳纳米管“天梯”,这都是“碳”性能展现的不同状态。本讲座将着重介绍闪光法导热仪测试常见碳材料(金刚石、碳纸、碳纤维、碳毡、碳砖、碳复合材料等)导热性能的测试方法及实例。 

Carbon is a magical and diverse material that is both the hardest and softest, an insulator and a conductor, a thermal insulation material and a thermal conductive material. Carbon materials serve in every aspect of life in a low-profile way, from the closest field of our life to the cutting-edge aerospace technology; from charcoal as a source of heat in the survival of human beings to the dazzling diamonds to express love; from the ink used for writing to open human civilization to the carbon nanotubes of the “heavenly ladder” for the expedition to the universe. These are the different states of carbon properties. This lecture will introduce the test methods and examples of Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity of common carbon materials (such as diamond, carbon paper, carbon fiber, carbon felt, carbon brick, carbon composites, etc.) by LFA.
