Abstract
AbstractThe transition from conventional polymeric material to green and sustainable, environment‐friendly biomaterials has been actively explored. The objective of the work involves the formulation of an oleo‐polymer (corn oil, CO), hybridization with metallic ions (Zn2+ and Mn2+) through coordination bonding, study of the impact of fully/half‐filled d‐orbitals, and development of eco‐friendly polymeric coating material. The formation of the nanoclusters (10–20 nm) within the polymeric matrix was estimated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Fourier transform infrared (FTIR) analysis supports the predicted chemical mechanism involved during poly‐urethanation of the metal‐containing CO fatty amides. Interestingly, opposite to our expectations the metal ions with fully filled d‐orbital (Zn2+) showed relatively (Mn2+) better thermal and anti‐corrosion properties. The good adhesive strength of metallopolymers and the impact of the d‐orbital electrons on the corrosion protective performance, which was by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP). These nanocomposite coatings could be a suitable alternatives to petrochemical‐based polymers.
