摘要：Superoxide Dismutase (SOD) was proposed as a potential scavenger of carbon radicals in ancient carbonized silk fabrics. Ancient and artificially carbonized silk samples were treated using this method. The optimal experimental conditions of the treatment were determined by variance analysis. The effects of the scavenging on carbonized silks were investigated by electron paramagnetic resonance (EPR). The results showed that the carbon radicals in both ancient and artificially carbonized silks were cleared to a great extent. The ageing resistance of the treated samples and scanning electron microscope (SEM) images of samples before and after treatment ensured that the treatment would not aggravate the deterioration of silk. Thus, the potential of SOD to scavenge carbon radicals in historic silk was demonstrated. Our research may help to alleviate further degradation which could occur during preservation of silk.
