A polystyrene (PS)-based fibrous color dosimeter, comprising a color former based on 2-(phenylamino)-6-(dipentylamino)-3-methylspiro[9H-xanthene-9,3′-phthalide] (Black305) fluoran leuco dye and a 2-(4-methoxystyryl)-4,6-bis(trichloromethyl)-1,3,5-triazine (MBTT) photoacid generator, was developed for visual detection of X-ray doses of 15 Gy and higher. The composite fiber was produced by using a centrifugal spinning method, and the obtained composite fiber exhibited a stable and uniform morphology with a fiber diameter of 10 μm or less and had sufficient mechanical strength. As an example of practical application, we successfully processed the composite fiber into an apron and clearly and visually confirmed that the color change from yellow to black occurs on the surface of the fabric under X-ray exposure.

基于Leuco染料的纤维颜色剂量计的X射线可视化和定量

一种基于聚苯乙烯（PS）的纤维色剂量计，其包含基于2-（苯基氨基）-6-（二戊基氨基）-3-甲基螺[9 H-氧杂蒽-9,3'-邻苯二甲酸酯]（Black305）荧光无色的成色剂染料和2-（4-甲氧基苯乙烯基）-4,6-双（三氯甲基）-1,3,5-三嗪（MBTT）光酸产生剂被开发用于视觉检测15 Gy或更高的X射线剂量。通过使用离心纺丝法制备复合纤维，并且所获得的复合纤维表现出稳定且均匀的形态，纤维直径为10μm或更小并且具有足够的机械强度。作为实际应用的一个例子，我们成功地将复合纤维加工成围裙，并在视觉上清楚地确认了在X射线照射下，织物表面发生了从黄色到黑色的颜色变化。
