摘　　要：以玉米秸秆(CS)为原料制备生物炭,并采用挤压法制备高密度聚乙烯/玉米秸秆生物炭(PE-HD/CSB)复合材料。研究了相容剂马来酸酐(MA)对PE-HD/CSB性能的影响。利用扫描电子显微镜(SEM)、热失重分析(TG)、傅里叶变换红外光谱(FTIR)、旋转流变仪(DHR-2)、X射线光电子能谱(XPS)等对CSB及复合材料进行了表征,并用Harmonic-Mean界面方程研究了CS和CSB同PE-HD的界面性能。结果表明,与CS相比,CSB的芳香化程度增加,且与PE-HD的界面张力更低,MA的加入提高了生物炭复合材料的稳定性、相容性及其力学性能。Corn stalk(CS)was used as a raw material to prepare biochar,and then the PE-HD/corn stalkr biochar(CSB)composites was prepared through melt extrusion.The compatibilizing effect of maleic anhydride(MA)on the performance of the PE-HD/CSB composites was investigated.The prepared CSB and the resultant composites were characterized using scanning electron microscopy,thermal weight analysis,Fourier-transform infrared spectroscopy,rotational rheometer(DHR-2),X-ray photoelectron spectroscopy.The interface properties of CS and CSB with PE-HD were evaluated using the Harmonic-Mean interface equations.The results indicated that compared to CS,CSB exhibited an increase in the degree of aromatization,and its interfacial tension with PE-HD was lower.The addition of MA improved the stability,compatibility,and mechanical properties of the PE-HD/CSB composites.
