Boehmite alumina (BAL) powder was investigated in terms of its use as a filler in PP in order to improve the inherent properties of recycled polypropylene. Nanocomposites of recycled polypropylene with different loadings of BLA were prepared by melt compounding technique. The structural characterization and morphology of BAL nanopowder were characterized by X-ray diffraction (XRD) and Transmission electron microscope (TEM). The influence of BAL nanoparticle content on the thermal properties of recycled polypropylene (PP) was studied by means of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The effect of the BAL content on the mechanical properties and morphological analyses (SEM) of recycled PP/BAL nanocomposites was also studied. It was found that BAL significantly affected the crystallization temperature and the degree of crystallization of recycled PP. The results showed that the BAL effectively improved the mechanical properties of recycled PP. In comparison with neat PP, the tensile strength of PP/BAL (3 wt%) nanocomposites increased by ~21% and the modulus increased by ~101%. Recycled polypropylene/boehmite alumina nanocomposites have such properties that advise their relevance for application in the packaging industries.
