Changes of PVC nanocomposite properties connected with clay content

Abstract

The polyvinylchloride (PVC) is an extensively used thermoplastic material, therefore the research were focused on this polymer. The aim of this work was to determinate the current development of nanocomposite materials based the polyvinylchloride and the influence of filler loading on their thermal and electrical properties. As nanofillers were used clays derived from montmorillonite (MMT): MMTNa+ and MMT30B. MMTNa+ presented sodium type of montmorillonite and MMT30 is organically modified type of MMT. Both of the clays were intercalated or cointercalated with plasticizer bis(2-ethylhexyl) phthalate (DEHP). As the compounder the Buss KO-kneader was selected. This type of compounder is suitable for processing temperature-sensitive polymers. The properties as thermal and electrical conductivity were evaluated in comparison to the structure.
