Nanocomposite of PVC with CNT

Poly(vinyl chloride) (PVC) with various advantages such as good chemically stability, biocompatibility and relatively low price could be one of the widely used polymers in industries. However, low electrical and thermal conductivity and poor mechanical strength have been the main problems of PVC limiting its practical applications sofar. Over the past decade, to enhance electrical and thermal conductivity and mechanical strength of PVC, a lot of research has been carried out using various nanofillers. Carbon nanotubes (CNTs) with high modulus (1 TPa), high strength (stronger than steel), high thermal stability (2800 °C in vacuum), excellent electrical conductivity (higher than copper), and high thermal conductivity (higher than diamond) are excellent candidates for PVC-based nanocomposites preparation as nanofillers. Recently, PVC/CNTs nanocomposites have received considerable attention as an interesting and important research area, worldwide. But, further research on optimization of the PVC/CNTs nanocomposites properties is necessary to find their future applications for practical uses. Current progresses in development of PVC/CNTs nanocomposites are being reviewed, in this chapter.
