Exposure to ionizing radiation (IR) during diagnostic medical procedures brings certain risks, especially when experiencing recurrent exposures. The fabrication of nano-based composites, doped with different nanoparticles, have been suggested as effective shielding materials to replace conventional lead-based ones in material sciences and nanotechnology. In this study, commercially available fabrics, used to produce scrubs and gowns for clinical staff, are modified utilizing graphene oxide (GO) nanoparticles using a layer-by-layer (LBL) technique. GO was obtained from graphite through environmentally friendly technology by using a modified-improved Hummers' method without NaNO. Lightweight, flexible, air- and water-permeable shielding materials are produced that are wearable in all-day clinical practice. The nanoparticles are kept to a minimum at 1 wt%; however, utilizing the LBL technique they are distributed evenly along the fibers of the fabrics to achieve as much shielding effect as possible. The evaluation of samples is accomplished by simulating real-time routine clinical procedures and the radiographic programs and devices used daily. The GO-coated nanocomposite fabrics demonstrated promising results for X-ray shielding.
在诊断性医疗程序中暴露于电离辐射（IR）会带来一定风险，尤其是在经历反复暴露时。在材料科学和纳米技术领域，已有人提出制备掺杂不同纳米颗粒的纳米基复合材料，作为有效的屏蔽材料来替代传统的铅基材料。在本研究中，利用氧化石墨烯（GO）纳米颗粒，采用层层（LBL）技术对用于为临床工作人员生产手术服和隔离衣的市售织物进行改性。通过使用改良的Hummers方法且不添加NaNO₃，采用环境友好型技术从石墨中获得GO。制备出了轻质、柔性、透气且透水的屏蔽材料，这些材料可在全天临床实践中穿着。纳米颗粒的含量保持在最低的1 wt%；然而，利用LBL技术，它们沿织物纤维均匀分布，以尽可能实现屏蔽效果。通过模拟实时常规临床程序以及日常使用的射线照相程序和设备来完成对样品的评估。涂覆有GO的纳米复合织物在X射线屏蔽方面显示出了有前景的结果。
