Porous lead-free x-ray shielding material and manufacturing method thereof

Abstract

A porous lead-free X-ray shielding material and a method for preparing the same are disclosed. The method for preparing the porous lead-free X-ray shielding material may include a first step of solidifying a mixture of sulfur-doped cerium oxide powders, a liquid PDMS binder, and a water-soluble precursor material for forming pores to form a solid, and a second step of dispersing the solid in water to form a plurality of pores therein. Thereafter, bismuth halide is loaded into the formed porous metal oxide structure, so that a composite material composed of the cerium metal oxide, PDMS, and bismuth halide may be finally obtained. In particular, the cerium metal oxide and bismuth halide are uniformly and densely distributed in the direction in which X-rays are irradiated, thereby enabling effective X-ray shielding.
