Individual carbon nanotubes(CNT) exhibit exceptional mechanical, electrical and thermal properties, offering considerable opportunity for the development of a new generation of advanced lightweight material. Due to difficulties in dispersing pristine CNTs in composites, attention is being increasingly drawn to direct assembly of CNTs into macroscopic fibers or sheets. Electron beam can be used to modify carbon-based materials through the introduction of functional groups on their surfaces, and consequently, improving the applicability of this material in polymer composites. In this study, the methodology to functionalize CNT yarns, via radiation process and using acrylic acid as a source of oxygen functional groups was investigated. The CNT yarns were submitted to direct grafting radiation process with electron beam. The modification of CNT fiber has been confirmed by x-ray photoelectron spectroscopy (XPS), Raman spectroscopy and scanning electron microscope (SEM).
