Tensile properties of millimeter-long multi-walled carbon nanotubes

There have been a number of theoretical and experimental studies on tensile properties of carbon nanotubes (CNT), reporting the Young’s modulus of the individual CNT up to 1 TPa. Although CNT shows the promise to be used as reinforcement in a high modulus/strength composite material, it exhibits qui...

description There have been a number of theoretical and experimental studies on tensile properties of carbon nanotubes (CNT), reporting the Young’s modulus of the individual CNT up to 1 TPa. Although CNT shows the promise to be used as reinforcement in a high modulus/strength composite material, it exhibits quite disappointing in terms of modulus or strength. Along with recent advance in CNT growth technique, we will be able to directly measure tensile properties of millimeter-long MWCNTs. This study firstly tackles the direct measurement of the tensile properties of millimeter-long MWCNTs that can be used as reinforcement in a composite system. A carefully designed tensile testing technique for the MWCNTs is developed, which allows us to obtain more accurate and reliable measured values. The average tensile strength and Young’s modulus of the CNTs investigated in this study are measured to be 0.85 GPa and 34.65 GPa, respectively. Also, this work statistically investigates the effect of the CNT dimensions including length, diameter and volume on the tensile properties. To the best of our knowledge, this is the very first report on the tensile properties of macroscopically long and continuous CNTs.
