摘要

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℃。

Abstract: 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℃).
