Mechanical, thermal, morphological and flammability properties of halloysite nanotube reinforced compatibilized poly(ethylene terephthalate) / polypropylene nanocomosities

The effects of two types of compatibilizers and halloysite nanotubes (HNT) on poly(ethylene terephthalate) (PET)/polypropylene (PP) blends were investigated. Blends of PET/PP in various compositions ranging from 20 – 50 wt% of PP were prepared via twin screw compounding. Polypropylene grafted maleic...
