摘要 研究以巨龙竹作为原料,采用环氧氯丙烷进行醚化改性,通过扫描电子显微镜(SEM)、X射线光电子能谱(XPS)、傅立叶变换红外光谱(FTIR)、X射线衍射(XRD)和热重分析(TG)对原料和改性材料的特性进行对比研究。结果表明,经过环氧氯丙烷改性后增重率为68%,材料醚键含量增加,XPS图谱中C-O键的峰强度增强。环氧氯丙烷改性提高了巨龙竹木质纤维的热稳定性,改性后物料的最大降解速率温度提升到374℃。 Making lignocellulose from renewable resources is all the rage.It has natural advantages in replacing petrochemical products.In this study,lignocellulose material from Dendrocalamus sinicus was modified with 6 mL epichlorohydrin at 120℃for 4 h.Characteristic of raw and modified materials was comparatively studied by scanning electron microscope(SEM)、X-ray photoelectron spectroscopy(XPS)、Fourier Transform Infrared Spectrometry(FTIR)、X-ray diffraction(XRD)and Thermogravimetric Analysis(TG).The results indicated that the weight of materials increased 68%after modified.With the increase of ether bonds in material,the peak intensity of C-O in XPS spectra increased.Modification with epichlorohydrin also increased the thermal stability of Dendrocalamus sinicus lignocellulose.The maximum degradation temperature of modified materials shifted to high temperature(374℃)as compared to the raw materials(315℃).
