Abstract
Reduced graphene oxide (rGO) was prepared by improved Hummer’s method and ternary metal oxide nano
composites (NCs) of Copper, Nickel, and Zinc oxide (CNZ) were synthesized by modified Sol-Gel techniques. rGO
and ternary CNZ NCs were grown together to get a flexible film. Their synergistic performance was investigated
in terms of anticorrosive, photocatalytic, magnetic, and opto-electric properties. A deeper comprehension of the
structural and optical characteristics of rGO/CNZ NCs was made by UV–visible, FTIR, p-XRD, SEM, and Raman
techniques. The average particle size observed from the XRD and SEM techniques was 80 nm. The NCs
demonstrated significant corrosion inhibition efficiency for mild steel with 99.01 % inhibition efficiency in 1.0 M

at 100 ppm concentration. A magnetic susceptibility (
χ
) of 0.257 indicates that the NCs are paramagnetic.
The electrical-band gap of NCs was 3.05 eV as observed from UV–vis. spectroscopy. The remarkable photo
catalytic efficiency for degrading Methylene Blue dye in 70 min. demonstrates the good photocatalytic efficiency
of the NCs. The rGO/CNZ NCs were flexible (bendable and rollable) showing their highly flexible nature, hence
