摘　　要：采用化学接枝的方法对麦秆纤维进行了改性研究，并对改性前后的麦秆纤维进行了红外光谱分析。结果表明，采用ＫＭｎＯ４、臭氧、臭氧－Ｆｅ＋２作为引发剂，均可以得到不同程度的麦秆纤维接枝产物；用臭氧－Ｆｅ＋２引发体系进行麦秆纤维丙烯酸接枝，在１７３０ｃｍ－１附近得到的－ＣＯＯＨ特征峰吸收强度要大于以ＫＭｎＯ４为引发体系所得到的特征峰吸收强度。Wheat straw fibers were modified by means of chemical grafting with different initiating agent And untreated fibers and modified fibers were analyzed by IR. The results show that grafting products for wheat straw fibers could be obtained using KMnO4 or H2O2 or H2O2-Fe+2 as initiating agent. In 1 730 cm-1 the absorbance of IR for modified wheat straw fibers using H2O2-Fe+2 as initiating agent is stronger than that using KMnO4 as initiating agent.
