| 摘 要： | 制备了含有螺噁嗪(SO)化合物的紫外光固化丙烯酸聚氨酯清漆(UV-PUA)膜, 研究了SO在该清漆中的光致变色性能, 并与其在聚甲基丙烯酸甲酯(PMMA)中的光致变色性能进行了比较. 结果发现, 紫外光固化螺噁嗪丙烯酸聚氨酯清漆(UV-SO-PUA)膜在紫外光固化过程中逐渐由无色变为蓝色和紫色, 撤去紫外光源, 漆膜退色至粉色, 且固化后的漆膜在粉色和紫色之间可逆变化; 而SO-PMMA膜在无色和蓝色之间可逆变化. 紫外光激发的UV-SO-PUA膜的紫外-可见吸收光谱可见光区出现了明显的双重吸收峰(520和600 nm), 而在PMMA中仅出现单峰. SO开环体在UV-PUA 中室温稳定性优于其在ＰＭＭＡ中的稳定性. SO在UV-PUA膜中的抗疲劳性能与其在PMMA中相比显著提高, 紫外光照射16 h, UV-SO-PUA漆膜未出现疲劳现象. SO在UV-PUA膜中表现出了优良的光致变色行为. |

| Abstract: | A UV-curable acrylic polyurethane(UV-PUA) lacquer film containing spirooxazine(SO) compound was prepared.Photochromic properties of the spirooxazine in the lacquer film and polymethyl methacrylate(PMMA) film were studied in details.It was found that the acrylic polyurethane lacquer film containing SO turned to blue,purple from colorless during the UV curing process.After removing UV light source,the film discolored to pink gradually and could change reversibly between pink and purple;while SO-PMMA film coul... |
