Abstract

Doping fluorescent substances in polymer matrices has shown promising applications as radiation dose sensors. In this work, quinoline dye based polyvinyl chloride fibrous films with fiber diameters of 123 nm, 540 nm and 864 nm were obtained by electrostatic spinning. The introduction of the fiber film structure makes the fluorescent film dosimeter flexible and lightweight compared to normal solid fluorescent films and further extends the linear range of X-ray detection to 0-350 Gy. Furthermore, the dosimeter shows energy and dose rate independence, and the sensitivity of the dosimeter can be improved by the application of fiber films with thinner diameters. This flexible fiber membrane provides a candidate material for wearable visual dosimeters.

通过静电纺丝实现灵活且与能量无关的荧光辐射纤维膜剂量计
在聚合物基质中掺入荧光物质作为辐射剂量传感器具有广阔的应用前景。在这项工作中,通过静电纺丝获得了基于喹啉染料的聚氯乙烯纤维膜,其纤维直径分别为 123 nm、540 nm 和 864 nm。与普通的固体荧光膜相比,纤维膜结构的引入使荧光膜剂量计更加灵活轻便,并将 X 射线检测的线性范围进一步扩大到 0-350 Gy。此外,该剂量计与能量和剂量率无关,并且可以通过应用直径更细的纤维膜来提高剂量计的灵敏度。这种柔性纤维膜为可穿戴式视觉剂量计提供了一种候选材料。
