Nanokomposite sind von großem industriellen und technologischen Interesse. In den letzten Jahren haben sie aufgrund ihrer Eigenschaftskombinationen schnell an Interesse gewonnen. Aufgrund der geringen Größe der Nanopartikel haben diese Materialien einen hohen Anteil an Grenzflächen (Interphase), was einen großen Einfluss auf die physikalischen Eigenschaften des Materials hat. Sie ermöglichen es, die Eigenschaften des Polymers (einfache Verarbeitung, geringes Gewicht usw.) mit denen des anorganischen Füllstoffs (optische und magnetische Eigenschaften usw.) zu kombinieren. Die in diesem Buch verwendeten Polymermatrizen sind zwei gesättigte Polyester, nämlich Polyethylenterephthalat (PET) und Polyethylennaphthalat (PEN). Die Methode zur Herstellung von PET/PEN/Ton-Nanokompositen in einem einzigen Schritt durch reaktive Extrusion wurde erfolgreich durchgeführt. Unbehandelter Ton wurde gereinigt und dann unter Verwendung von drei grundlegenden Reagenzien, nämlich Peroxid, Schwefel und einem spezifischen Beschleuniger, aktiviert. PET und PEN wurden getrennt in geschmolzenem Zustand mit reaktivem Ton vermischt. PET/4 wt% Ton und PEN/7,5 wt% Ton zeigten eine vollständige Exfoliation.
