摘要

合成了线性和支链聚乳酸，并在其基础上用硝基取代吲哚吡喃制备了光致变色聚合物涂层。光谱动力学实验表明，这些涂层具有正、负光变色特性。支化聚乳酸的含量决定了光致变色的外观特征。

Spectral Manifestation of Positive and Negative Photochromism in Polylactide Layers

Linear and branched polylactides were synthesized, and photochromic polymer coatings on their basis were obtained using nitro-substituted indoline spiropyran. Spectral-kinetic experiments showed that these coatings can exhibit both positive and negative photochromism. The character of appearance of photochromism is determined by the content of branched polylactide.
