Description:
To improve the interfacial adhesion of bamboo powder (BP) and polypropylene (PP), the effects of zirconaluminate coupling agent (TL) on the mechanical properties, rheological behavior and thermal stability of 33 wt% injection moulded BP/PP foaming composites were investigated. The bending and tensile properties were enhanced first as the TL content increased and then decreased as the TL content exceeded 1 %; the notched impact strength improved steadily with increased TL content. The 1 % TL-treated composite showed the best comprehensive mechanical properties; the bending, tensile, and notched impact strengths were increased by 9.0, 9.7, and 16.1 %, respectively; and water absorption for 1,920 h was decreased from 8.85 to 2.61 % compared to the untreated composite. The frequency sweep results indicated that the slope of lg G ′–lg f curve increased from 0.709 in the untreated composite to 0.842 in the 1 % TL-treated composite. The TG results revealed that thermal stability was slightly improved in the TL-treated composite. Environmental scanning electron microscopy showed that the interfacial compatibility of the treated composite improved, which was confirmed by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy analysis.
