- 中文摘要: 本文主要論述本實驗室近年來所合成之各類高熱穩定性之新型光變色色素-spirooxazines及其在高分子基材中之變色機能。這些光變色色素具有極優越的變色機能,與pp、PET、Nylon-6等高分子摻混後,即使色素濃度僅佔0.1wt%,仍能製得變色效果極佳的光變色纖維。文章中,我們除了描述各類新型spirooxazines外,並提出一項模式函數來研究這些光變色色素在不同高分子基材中的光著色及光消色之動力現象。
- 英文摘要: This paper gives a review of our recent work concerning photochromism of spirooxazines in polymermatrices. Novel spirooxazines with higher decomposition temperatures have been synthesized. Thesespirooxazines have excellent photocoloration capabilities even at concentrations as low as 0.1 wt % whendoped in PP, PET, and Nylon-6 to manufacture photochromic fibers. A general model is proposed tostudy photocoloration and thermal decoloration of spirooxazines in polymer matrices in order to explainthe environmental effects around the photochromic molecules.
