| Abstract |
| This research examines the advancement of novel multilayered polymer composites as a lead-free alternative for X-ray attenuation. Using a pad-dry method, gelatin-BaSO4 composite coatings were put on polyester and cotton fabrics to make radiation shielding materials that are light and flexible. We looked at how the concentration of BaSO4 (6–12% w/v), the number of coating layers (1–5), and the energy levels of the X-rays (60–120 keV) affected attenuation efficiency. FTIR analysis showed that gelatin and BaSO4 particles physically interacted with each other. SEM imaging showed that BaSO4 was evenly spread throughout the polymer matrix. Adding more BaSO4 and layers made X-ray attenuation much better. A 5-layer 60% w/w BaSO4 coating blocked 84.73% of X-rays at 60 keV. With more BaSO4, the thermal stability went up, and the decomposition temperatures for 60% BaSO4 composites reached 498°C. The coatings were hydrophobic, which made them last longer. Even though the tensile strength went down a little, the composites still had enough flexibility for real-world use. This study shows that BaSO4-based multilayer composites could be good, eco-friendly substitutes for lead in medical, industrial, and nuclear radiation protection. |
