Preparation and Characterization of Electrospun Fibers of Poly(methyl methacrylate) - Single walled carbon nano-tube Nanocomposites

摘要

Electrospinning is a versatile method of preparing polymer nanocmposite fibers. Electrospun nanocomposite fibers of poly(methyl methacrylate) and single walled carbon nanotubes were prepared. The fibers were characterized by SEM, TEM, TGA and Raman spectroscopy. These fibers show dramatic improvement in the electrical conductivity compared to the polymer. The temperature dependent electrical resistance measurements show a one dimensional variable range hopping model (1-D VRH) type of conduction mechanism operating in these types of systems.
