Abstract
AbstractFaced with the presence of radiation sources in many different areas, researchers are beginning to focus on the development of personal protective equipment. The design and manufacture of lightweight, lead‐free, and flexible X‐ray shielding materials have recently become a challenge in materials science, whereas, high‐Z materials, which are essential raw materials for high‐performance X‐ray protective fillers, are non‐renewable, and their exploitation and utilization usually require long‐term planning. In this study, a new route is demonstrated to the preparation of multifunctional polymer/high‐Z material nanofibrous membrane through electrospinning and subsequent solvothermal processes. The resultant Bi2WO6/WO3/polyacrylonitrile hybrid nanofibrous membrane possesses a remarkable X‐ray attenuating property with an attenuation rate of 90.10% at 30 keV and a mass attenuation coefficient of 2.97 cm2 g−1 at 83 keV. In addition, the freestanding hybrid nanofibrous membrane also possesses excellent photocatalytic activities for the degrading of cationic water pollutants, showing promising potential in industrial wastewater treatment, and providing a new strategy for the design and applications of multifunctional and recyclable shielding materials.
