Abstract

Recycling polyethylene terephthalate (rPET) offers significant environmental and economic benefits; However, its mechanical and thermal properties deteriorate during processing. To address these challenges, blending rPET with polyamide 11 (PA11) and reinforcing it with nanofillers such as sepiolite and graphene nanoplatelets (GNPs) were investigated. This review provides an overview of the mechanical and thermal improvements achieved by these blends and highlights the potential applications of rPET/PA11 nanocomposites. At optimal proportions of PA11 and nanofillers, improved tensile, flexural and impact strengths were observed, presenting significant prospects for industrial applications in the automotive and packaging industries.
