Abstract: This thesis aims to comprehensively investigate the mechanical, electrical and thermal properties of the CNT fibers and films fabricated by the floating catalyst method and to develop the advanced CNT-polymer composites for practical applications. A steady-state Joule heating infrared metrology technique was successfully developed to simultaneously investigate the thermal conduction and convective heat transfer in the CNT fibers and films. The effects of various synthesis conditions on the multi-properties of the CNT fibers and films were quantified comprehensively. After the mechanical condensation and acid treatment, the tensile strength, electrical and thermal conductivities of the CNT fibers and films were enhanced significantly. In particular, the acid-treated CNT films demonstrated both high absolute thermal conductivity and specific thermal conductivity which were even higher than those of copper and aluminum. The CNT fibers and films were further developed into the CNT/polyimide aerogel composite fibers and CNT/epoxy composite films for electrical and thermal applications.
