Recycled poly(ethylene terephthalate)/layered silicate nanocomposites: morphology and tensile mechanical properties


Various amounts (1, 3 and 5 wt%) of a non-modified natural montmorillonite clay (Cloisite Naþ) or of an ion-exchanged clay modified with quaternary ammonium salt (Cloisite 25A) were dispersed in a recycled poly(ethylene terephthalate) matrix (rPET) by a melt intercalation process. Microphotographs of composite fracture surfaces bring evidence that particles… (More)
