Abstract:
Poly(ethylene terephthalate) (PET) nanocomposites
with single-walled carbon nanotubes (SWNTs) have
been prepared by a simple melt compounding method. With
increasing concentration (0-3 wt %) of SWNTs, the mechanical
and dynamic mechanical properties improved, corresponding
to effective reinforcement. Melt rheological characterization
indicated the effective entanglements provided by SWNTs in
the melt state as well. Thermogravimetric analysis suggested no influence of SWNTs on the thermal stability of PET. Electrical
conductivity measurements on the composite films pointed
out that the melt compounded SWNTs can result in electrical
percolation albeit at concentrations exceeding 2 wt %.
