Nanocomposites of poly(vinyl chloride) with carbon nanotubes (CNT)

The nanocomposites of PVC with multi-walled carbon nanotubes and single wall carbon nanotubes were prepared in THF solution, followed by film casting. The scanning electron microscopy allowed to confirm a homogeneous distribution of the CNT’s in the PVC matrix. Depending on the CNT’s concentration, changes of sorption in methylene chloride as well as of the characteristic temperature of PVC transformation, determined by means of the DSC measurements, were found. The electrical measurements indicated an increase of the conductivity with growing CNT’s content in the PVC matrix.
