High-Modulus Poly(ethylene terephthalate)/Expandable Fluorine Mica Nanocomposites with a Novel Reactive Compatibilizer

Abstract

High modulus poly(ethylene terephthalate) (PET)/layered silicate nanocomposites were prepared by employing a novel reactive compatibilizer, 10-[3,5-bis(methoxycarbonyl)phenoxy]decyltriphenylphosphonium bromide (IP10TP), which was designed to link the layered silicate to the PET matrix through covalent and ionic bonds. The obtained nanocomposites showed a 70% higher flexural modulus than a raw PET at maximum.
