Synthesis, characterization and bioactivity of chalcone-based polybenzoxazine/copper oxide nanocomposites.

ABSTRACT: In the current work, a chalcone-based benzoxazine monomer was synthesized by Mannich condensation reaction using octadecylamine, paraformaldehyde, and a hydroxylated chalcone in a co-solvent of toluene/ethanol. The resulting benzoxazine monomer was mixed with nanoparticles of copper oxide at different ratios to obtain polybenzoxazine/copper oxide nanocomposites. The structure of the benzoxazine monomer was verified using FTIR and ¹H NMR, while the structure of polybenzoxazine/copper oxide nanocomposites was investigated using FTIR and XRD. The morphology of the resultant composites was examined using SEM and TEM. The thermal properties of polybenzoxazine/copper oxide nanocomposites were studied using TGA. The resulting composites were tested for antibacterial activity against so
