Renewable Resource-based Composites of Thermoplastic Acorn Kernel and Polycaprolactone: Preparation and Properties Evaluation
Renewable resource-based thermoplastic acorn kernel(TPAK) were prepared by twin-screw extrusion method. And TPAK/PCL composites were also prepared with the same method followed by injection molding processing. The morphology, hydrophobic, mechanical and thermal properties of the composites were investigated by scanning electron microscopy(SEM), tensile test, moisture absorption, dynamic mechanical thermal analysis(DMA), differential scanning calorimetry(DSC) and thermogravimetric analysis(TGA). The microscopic study on the microstructure of the composites showed poor adhesion between TPAK and PCL. DSC, DMA and TGA results showed that the presence of TPAK significantly affected the crystallinity, glass transition temperature(Tg), melting temperature(Tm) and the thermal decomposition temperature of PCL matrix. In this study, composites did not show any difficulties in the extrusion and injection molding process. It indicated the feasibility of scalable production of the TPAK/PCL composites with renewable acorn materials. The study results proved that TPAK/PCL composites had superior mechanical properties, which can partially replace the conventional thermoplastic plastics.
