Coelectrospinning of Carbon Nanotube Reinforced Nanocomposite Fibrils

In order to assess the potential of carbon nanotube (CNT) for structural composite applications, a method was proposed to convert CNT to continuous fibrils and fibrous assemblies using the co-electrospinning process. Preliminary experiments demonstrated the feasibility for the formation of composite CNT fibrils. These fibrils provide a convenient material form to carry the CNT and facilitate the formation of macro composite structures. The level and the nature of CNT and fiber alignments, and the inclusion of CNT in the nanofiber were elucidated through SEM, TEM observations and Raman spectra analysis. Mechanical testing of the nanofibril, nanofibril spunbonded mats and composite yarns were carried out to assess the effect of fibril alignment and verify the nancomposite fibril concept.
