HDPE nanocomposites using nanoclay, MWCNT and intumescent flame retardant characteristics

Nanocomposites of high density polyethylene (HDPE) along with nanoclay (NC), acid functionalized multiwalled carbon nanotubes (MWCNT) and pentaerythritol phosphate (PEPA) have been developed. In order to enhance the interfacial adhesion, HDPE grafted glycidyl methacrylate has been added to the composites. An improvement in mechanical properties and flammable characteristic for the nanocomposites has been observed using both nanoclay and MWCNT and was further analysed using micromechanical models.
