To simply and multitudinously synthesize hollow microspheres in a pure system is important for relevant research and application. Here, a simple and novel one-pot synthetic strategy to prepare polystyrene (PS) hollow microspheres via irradiation-assisted free-radical polymerizing and self-assembly (IFPS) approach under γ-ray irradiation with no additives introduced into the system is presented. And PS/2,5-Diphenyloxazole (PPO) fluorescent microspheres have been prepared successfully by IFPS reaction, which can be used as scintillators for the detection of ionizing radiation. A linear relationship between emitted luminescence and dose-activity in water is obtained, which suggests that composite microspheres could be used as liquid scintillation in specific environment.
简单而大量地在纯体系中合成中空微球对于相关研究和应用很重要。在这里，我们提出了一种简单新颖的一锅法，通过γ射线辐照下的无添加剂自由基聚合和自组装（IFPS）方法制备聚苯乙烯（PS）中空微球。并且通过 IFPS 反应成功制备了 PS/2,5-二苯并恶唑（PPO）荧光微球，可用作电离辐射检测的闪烁体。在水中，发射光与剂量活性之间存在线性关系，表明复合微球可在特定环境中用作液体闪烁体。
