preparation and properties of co-continuous pc/pet/mwcnt/gnp engineering polymer blend nanocomposites

This study reports on the preparation and characterization of nanocomposites based on polycarbonate (pc)/poly ethylene terephthalate (pet) blend containing low contents of hybrid of multiwalled carbon nanotube (mwcnts) and graphene nanoplates (gnps) by melt mixing. to use double percolation mechanism, at first a co-continuous polymer blend was prepared sample containing 60 wt. % pet showed co-continuous morphology as observed by scanning electron microscopy .the direct current (dc) electrical conductivity results showed a low electrical percolation threshold around 0.5%wt. the tensile measurements results showed that the addition pc to pet increases the tensile strength of pet. thermal stability of pure blend was improved by addition of hybrid naocomposites.
