    • Abstract

       

      New inherently radiopaque nanocomposites were prepared using iodine-containing poly(methyl methacrylateco-acrylamide) and graphene oxide. For this purpose, P(MMA-$co$-AA) was synthesized via copolymerization of methylmethacrylate and acrylic acid, and modified with 4-iodophenyl isocyanate and 3,4,5-triiodophenyl isocyanate to form poly[(methyl methacrylate-$co$-(N-4-iodophenyl)acrylamide)] (1I-P(MMA-$co$-AA)) and poly[(methyl methacrylate-$co$-(N-3,4,5-triiodophenyl)acrylamide)] (3I-P(MMA-$co$-AA)), respectively. For comparative evaluation, the non-iodinatedcopolymer (PIC-P(MMA-$co$-AA)) was prepared via reaction of the P(MMA-$co$-AA) with phenyl isocyanate to investigate the effect of iodinated substituents on the morphology and thermal characteristics of the nanocomposites. All the nanocomposites were characterized by X-ray diffraction analysis, scanning electron microscopy, X-radiography and thermogravimetricanalysis. The results proved that thermal properties of the nanocomposites improved by the introduction of different amounts of graphene oxide into the copolymers’matrix. Radiopacity measurements showed the excellent radiopacityof iodinated nanocomposites and proved that 3I-GO-5 had radiopacity equivalent to that of an aluminium wedge with 2-mm thickness.
