X-rays’ high-energy nature poses risks to human health. Traditional X-ray shielding materials often contain toxic lead and have drawbacks like bulkiness rigidity. Consequently, there is an increasing need develop lightweight, non-toxic, flexible, efficient materials. In this study, we modified barite with waterborne polyurethane (WPU) systematically investigated the effects of WPU on barite’s properties. The modification not only reduced tendency (B) agglomerate but also enhanced its compatibility polymers, thereby significantly improving mechanical properties LDPE/WPU-B composites. Compared unmodified in LDPE/B composites, tensile flexural modulus composites increased by 22.31% 29.64%, respectively. With 20% WPU-modified barite, radiation efficiency 5%. When WPU-B content reached 40%, composite exceeded 90% for tube voltages ranging from 60 kV 120 kV, achieving a equivalent 0.38 mmPb at 100 kV. This novel has great potential low-dose applications.
