Expandable polyamide-6/graphite composite (P-6/GC) is a newcomposite. Expandable P-6/GCis providedwith the exfoliated propertywhile is heated at 300oC. Owing to using an expandable reagent containing graphite carbon, electron transfers property of P-6/GC exfoliated has been strengthened. Infrared spectrumis applied to attest polyamide-6 on graphite worm. Images of scanning electron microscope show worm-like morphology of P-6/GCexfoliated.Comparing the volume resistivity of expandable P-6/GC to P/-6GCexfoliated, the result is that P-6/GC exfoliated has stronger electron transfers than expandable P-6/GC.
