摘要
采用高碘酸钠对竹原纤维进行选择性氧化,探讨了竹原纤维大分子上的羟基被氧化成醛基的过程,并用红外光谱、X衍射等手段分析了氧化竹原纤维的聚集态结构。结果表明,增大氧化剂浓度可以提高高碘酸钠对竹原纤维的氧化程度,使醛基含量增加;氧化后竹原纤维的结构发生改变,为竹原纤维进一步功能改性提供了反应位点。
In this article, original bamboo fiber is prepared by selective oxidation with sodium periodate. The process of hydroxyl groups on original bamboo fiber macromolecules which are oxidized to aldehyde groups is explored. The aggregation structure of original bamboo fiber oxidized with periodate is analyzed by means of FT-IR and XRD. The results show that the number of aldehyde groups has increased with the increase of oxi- dantg concentration. The structure of oxidized original bamboo fiber has been changed, which provides reac- tion - site for sequent treating of original bamboo fiber.
