ABSTRACT The current approach represents a synthetic technique for developing novel core-shell nanocomposites (CSNCs) based on titanium dioxide. TiO2@poly(anthranilic acid-co-o-phenylenediamine) (TiO2@PANA-o-PDA) CSNCs were synthesized by applying varied loads of TiO2 and the fivefold molar ratio of the proper monomers via polycondensation. The newly synthesized TiO2@PANA-o-PDA CSNCs were confirmed by different characterizations. The linkage between PANA-o-PDA and TiO2 was observed in the FT-IR spectra. The CSNCs structures have core-shell features possessing sizes 17–27 nm. Under sunlight irradiation, these CSNCs demonstrate significant photocatalytic activity toward MB dye degradation. Appropriate clarifications of the photocatalytic efficiency results were explicated. The PDI, y-intercept, and ζ of a particle were estimated by DLS for the copolymer colloidal system. This protocol manipulates the cheap, essential, as well as beneficial synthetic setup to produce unique CSNCs as novel potential formulations. GRAPHICAL ABSTRACT HIGHLIGHTS Novel TiO2@PANA-o-PDA core-shell nanocomposites were successfully synthesized. Cheap monomers were utilized by fivefold molar ratio via economical technique. TiO2@ PANA-o-PDA core-shell was thermally stable than pure copolymer. TEM revealed core-shell nanocomposite structures with sizes 17-27 nm. By DLS, narrow PDI with a good system is clarified. TiO2 lowers the electrical conductivity of the core-shell nanocomposites. Photocatalytic efficacy of the MB degradation was elucidated.
