Morphologies and Properties of Virgin and Waste PP Nanocomposites

Abstract

Polypropylene is a semicrystalline thermoplastic addition polymer used in several applications, such as plastic parts for many industries, consumer product packaging, special devices like living hinges, and textiles. Thanks to its excellent properties, it could be used only or in a nanocomposite system. This article presents the different types of nanoparticles used for the enhancement of thermo-mechanical and physical behaviors of PP nanocomposites. The analysis of morphologies and thermo-mechanical behaviors of virgin PP nanocomposites are described. Moreover, this paper also discusses the improvements of properties of waste PP by nanoparticle incorporation. Finally, the last section of the paper covers a case study about influence of clay nanoparticles on waste PP based nanocomposites.
