This study's primary objective was to evaluate the X-ray shielding efficiency of PET fabric coated with bismuth oxide/poly (vinyl alcohol) (Bi2O3/PVA) nanofiber. For this purpose, bismuth oxide (Bi2O3) nanoparticles were synthesized by hydrothermal method. Then, the nanomats containing poly (vinyl alcohol) (PVA) polymer in different weight fractions of Bi2O3 nano- and microparticles by electrospinning technology were coated on PET fabric. The photocatalytic efficiency was estimated by the degradation of methylene blue dye under UV light illumination. Finally, the prepared samples containing different weight fractions of Bi2O3 nano- and microparticles were exposed to an X-ray tube in a radiography system at different voltages. Attenuation characteristics such as the linear attenuation coefficient and the half-value layer of PVA nanocomposites concerning X-ray radiation were studied. Results revealed that the X-ray radiation shielding performance of Bi2O3/PVA nanofiber composite-coated polyester fabrics was better than that of undoped PVA nanofiber-coated ones. X-ray attenuation increased with the increment of Bi2O3 loading. Also, the results indicated that the fabric treated with Bi2O3 nanoparticles could degrade methylene blue dye photocatalytically. This research has shown that PET fabric coated with nanocomposites containing Bi2O3 nano- and microparticles with a suitable percentage can be effective for X-ray attenuation.
