polypropylene wood flour composites

this study melt-blends polypropylene (pp), wood flour (wf), and far-infrared masterbatches into pp/wf wood plastic composites with far-infrared emissivity. during the process, maleic anhydride-grafted polypropylene (pp-g-ma) is added as the coupling agent between pp and wf. mechanical property .
