  Abstract

With the advancement of society and technology, people are increasingly exposed to invisible sources of radiation in daily study, work, and life-such as mobile phones, televisions, computers, medical imaging equipment, and industrial radiographic instruments. There is now an urgent demand for environmentally friendly, lightweight, and flexible X-ray shielding materials. In this study, polypropylene (PP)–Bi₂O₃ and PP–WO₃ composite fibers were prepared by melt spinning, and, innovatively, Bi₂O₃, Gd₂O₃, and WO₃-three high-atomic-number fillers-were synergistically incorporated into the PP matrix in a single melt-spinning step to produce flexible fabrics. The materials were systematically characterized by X-ray shielding tests, scanning electron microscopy (SEM), single-fiber tensile testing, Fourier-transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and fabric breathability test. The results demonstrate that these fabrics achieve good X-ray shielding performance in the 15–40 keV energy range. The materials combine low weight, high strength, and good thermal stability, can be produced at scale without complex post-processing, and show significant potential for application and market translation in medical diagnostic protection.
