X-ray radiation shielding and microscopic studies of flexible and moldable bandage by in situ synthesized cerium oxide nanoparticles/MWCNTS nanocomposite for healthcare applications.

This research reports a robust method for developing advanced flexible and moldable X-ray shielding bandages by harnessing an in situ synthesized polygonal cerium oxide nanoparticles/MWCNTs nanocomposite. The developed advanced hybrid nanocomposite was thoroughly blended with silicone rubber, namely polydimethylsiloxane (PDMS) to form an advanced hybrid gel which was then coated on a conventional cotton bandage to develop an advanced flexible, moldable X-ray shielding bandage. The combined effects were analyzed to determine their unique X-ray reduction properties and were very effective. The linear attenuation value of the developed bandage (untreated cotton bandage coated with CeO 2 /MWCNT/PDMS), varied from 1.274 m -1 to 0.549 m -1 and the mass attenuation values from 0.823 m 2 kg -1 to 0.354 m 2 kg -1 for kVp 40 to 100 respectively. The improved features of high density and efficiency of protection are because of the binary protective effect of CeO 2 nanoparticles and MWCNT. The morphological features of the developed material were characterized using various techniques such as TEM, SEM, XRD, and EDXA. The developed bandage is an entirely lead-free product, thin and light, has high shielding performance, flexibility, durability, good mechanical strength, doesn't crack easily (no crack), and can be washed in water. It may therefore be useful in various fields, including diagnostic radiology, cardiology, urology, and neurology treatments, attenuating emergency radiation leakages in CT scanner rooms or via medical equipment, and safeguarding complex shielding machinery in public areas.
