Investigations on preparations and electrical conductivity of PA-66/OMMT nanocomposites
Organoclay has a low electrical conductivity and a proper dielectric constant which makes it to be used as a gate insulator.In a dry form,the organoclay exists in aggregates of montmorillonite platelets and very little surface area of the montmorillonite is exposed.For uniform dispersion of the clay aggregated,PA-66 and organically modified Na-montmorillonite (OMMT) were melting blended by using an internal mixer.The crystalline change and effects of intercalation were investigated with X-ray diffraction.Results of thermal properties,micro-structure,surface resistance and crystallization behavior indicated that OMMT had obviously effects on PA-66.DSC results showed that the existent of OMMT had effect on PA-66/OMMT nanocomposites and OMMT content had important effects on the scatter of OMMT in PA-66 matrix.
