Carbon Nanotube Nanocomposites by Electrospinning

초록

Nanofibers of poly(methyl methacrylate) (PMMA) nanocomposites containing well dispersed multi-walled carbon nanotube (MWNT) were prepared via an in-situ bulk polymerization of methyl methacrylate (MMA) in the presence of carbon nanotubes (CNTs), followed by the electrospinning process. Dispersion of the CNTs in the electrospun nanofibers was far superior to the conventional polymer composites with CNTs dispersed using surfactants. MWNTs in the nanofibers were found to align along the fiber axis. Surface morphology and electrical conductivity of the electrospun nanofiber of PMMA/MWNT nanocomposites were invesrigated as a function of the MWNT content.
