  • Abstract The purpose of this study is combining multi-walled carbon nanotubes with the traditional fibers to develop the high added value of conductive fibers.
    Carbon nanotubes are the thinnest tubes people ever know. Besides the properties on physical and chemical, they also have outstanding performances with high thermal conductivity, high strength, good electrical conductivity, high flexibility, and chemical stability. This study will use with or without purified carbon nanotubes and introduce them into the fibers with different concentrations. The carbon nanotubes polymer composite as new functional fibers are developed to examine its structures and properties. The fibers contain the properties of carbon nanotubes such as high thermal conductivity, high strength, good electrical conductivity, and high flexibility. With connecting to the power supply, it can be used as thermal textile fibers, which can add on the value of fibers in the applications of clothing, decoration, and textile products.
    According to the results in this study, the conductivities of nanocomposites increase with the amounts of MWCNTs added in PET. MWCNTs/PET nanocomposite with 4wt.% MWCNTs has higher electrical conductivity, and better capable of electromagnetic shielding. The results also indicates the MWCNTs/PET with 3 wt.% purified MWCNTs doesn’t show better performance than that of 3 wt.% as-prepared MWCNTs/PET, which may due to the aggregation of MWCNTs during acid treatment.
