含碘仿的聚N-乙烯咔唑的激光变色效应

Study on Laser-induced Color-changing Reaction of PVK-CHI_3

用脉冲Ｎｄ：ＹＡＧ激光器作光源，研究了含碘仿的聚Ｎ－乙烯咔唑体系的光变色效应，测量了激光参数及聚Ｎ－乙烯咔唑的分子量对体系变色效应的影响，观测了含碘溶剂的增色效应，对体系的变色反应机理进行了探讨。

In this paper, color-changing reaction of PVK-CHI3 under the radiation of pulse Nd: YAG laser is studied. The color-changing affection versus the experimental conditions is investigated. The color-enhancement affection of containing I2 is also observed. The PVK-CHI3 color-changing reaction is interpreted mechanistically.
