Thermal and Structural Characterization of Furfuryl Palmitate Coated Fly Ash Reinforced Recycled Polypropylene Matrix Composites

Abstract:

Abstract: The fly ash (FA) particles were coated with furfuryl palmitate (FP) in different weight % like 1, 2, 3 and 5. The FP coated fly ash particles were incorporated as filler in recycled polypropylene (RPP) matrix composites by melt mixing in 1:1 weight ratio. X-ray diffraction (XRD) analysis, Dynamic Mechanical Analysis, Differential scanning calorimetry (DSC), and Thermogravimetric analysis (TGA) of the composite samples were carried out. The presence of the coupling agent FP resulted in changes in the packing order and structural properties of the composites. It also influenced the alignment of RPP molecules with better filler –matrix interaction in 2 wt % FP coated composite as ascertained from the DSC and DMA analysis. Distinct shift in the glass transition temperature was also observed in 2 wt % FP coated composite samples. However significant improvement in the thermal stability was not observed. Thus, an unconventional, renewable, low cost coupling agent FP was found to influence the structural and thermal properties of the RPP/FA composites significantly.
