摘要
本文研究了电子束辐照降解固态羧甲基纤维素(CMC)效应。结果表明:辐照CMC固体样品配制2%水溶液粘度随着辐照剂量增大而减少;红外光谱分析表明,辐照导致CMC分子链上糖苷键C1-O-C4断裂。固态CMC辐照降解符合无规则降解动力学规律。
In this work, electron beam degradation of carboxymethyl cellulose （CMC） in solid state was investigated. The results showed that viscosity of the irradiated CMC in 2% aqueous solution decreased with increasing doses. FT-IR characterization of the CMC samples before and after irradiation showed that the irradiation of 40 kGy can lead to rapid breaking off of the glucoside bond （C1-O-C4）. The irradiation degradation of CMC in solid state obeys the rule of random degradation.
