4. Polyester-based lamellar nanocomposites

This paragraph describes the different strategies for obtaining lamellar nanocomposites based on PET or poly (ethylene terephthalate), as well as their properties and directly targeted fields of application.

PET is a semi-crystalline thermoplastic polyester that first developed in the textile and automotive industries in the form of yarns and fibers, before expanding into the food packaging industry in the form of films or hollow bottle-like bodies, where PET gradually replaced glass and PCV in the packaging of mineral water and carbonated drinks to become virtually the only polymer used in this market today. The strong growth of this "commodity" polymer is due to its excellent intrinsic qualities, namely transparency, absence of coloring, excellent thermomechanical and gas-barrier properties, not to mention its ability to crystallize under stretching, enabling...
