阳离子染料在真丝绸上的光褪色机理
摘要:
用电化学循环伏安法研究真丝绸上染料的光褪色,发现真丝绸中的某些氨基酸和染料、氧分子3者间可以形成电荷转移复合物。这些三元电荷转移复合物的还原电位比染料本身的还原电位明显正移。用λmaxCTC的光照射,证明是真丝绸中的氨基酸加速了阳离子染料的光褪色。

Fading Mechanism of Cationic Dyes on Silk
Abstract:
Cyclovoltametric results showed that there exist charge transfer complexes (CTC) consisted of cationic dyes,amino acids and molecular oxygen which possess more positive re-duction potentials or higher peak currents than dyes.Irradiating the CTCS at their λmaxCTC reveals that it is the amino acids of the silk that accelerate the light fading of the dyes.
