Abstract
AbstractWe report here the development of multifiller nanocomposite containing gadolinium oxide and bismuth nanofillers with enhanced X‐ray attenuation property. The mass attenuation coefficient of the nanocomposite is found to be 5.26 (X‐ray attenuation: 95%) and 2.22 cm2/g (X‐ray attenuation: 71%), respectively, under dental and lung X‐ray scan conditions. Fourier transform infrared spectroscopy confirms the interfacial interaction between Gd2O3 nanofillers and the polymer matrix through hydrogen bonding. Atomic force microscopy images of the nanocomposite show a smooth and uniform topography with an average surface roughness of ~19 nm. Thermogravimetric analysis confirms the thermal stability of the nanocomposite upto 384°C. The enhanced X‐ray attenuation property of the nanocomposite is attributed to the good interfacial bonding, dual k‐edge effect of nanofillers and their uniform distribution within the polymeric matrix. Therefore, this nanocomposite is a promising material for diagnostic X‐ray shielding, especially as, thyroid collar, gonad shield, aprons, gloves, and so on.
