Abstract :
This recent study investigates the properties of recycled polypropylene (RPP)/peanut shell powder (PSP) composites under the effect of alkaline peroxide pre-treatment. RPP/PSP composites were prepared by melt-mixing and compression molding with 0 to 40 wt % of PSP loading. The untreated RPP/PSP composites and treated RPP/PSP/H2O2 composites were compared and characterised by tensile properties, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The results showed that the treated PSP enhanced the tensile and thermal properties of RPP/PSP/H2O2 composites while the FTIR spectra and SEM morphology presented the elimination of lignin content strongly influenced the fractured surface and chemical characteristics of the RPP/PSP/H2O2 composites.
