该研究评估了稳定剂与用于电子可调光材料的染料掺杂液晶（LC）支架的相容性。研究了材料的光降解，并评价了合适的稳定剂以减缓降解过程。评价各种类型的苯并三唑基稳定剂用于稳定液晶。基于自旋捕获实验，UV曝光后产生的自由基可能是系统退化的原因。通过添加稳定剂竞争性抑制自由基生成。
The study evaluates compatibility of stabilizers with dye doped liquid crystal (LC) scaffolds that are used in electronically dimmable materials. The photodegradation of the materials was investigated and suitable stabilizers were evaluated to slow the degradation process. Various types of benzotriazole‐based stabilizers were evaluated for stabilizing the liquid crystals. Based on spin trapping experiments, radicals generated upon UV exposure is likely responsible for the degradation of the system. The radical generation is competitively inhibited by the addition of stabilizers.
