Abstract

Purpose

The purpose of this study to investigate the synthesis of new Cr(III), Fe(III), Ni(II) and Cu(II) Schiff base complexes by a simple technique (microwave technique). The evaluation of the prepared complexes as pigments as corrosion resistant was also explored.

Design/methodology/approach

The Schiff base complexes were prepared by using microwave method (green chemistry), and then, the physico-chemical requirements according to standards for the synthesised pigments were investigate.

Findings

The prepared complexes exhibit good physical, mechanical and corrosion properties as pigments in paint formulations.

Research limitations/implications

The simple technique used for synthesis of metal complex pigments will significantly increase the cost saving for the manufacturing of such pigments category. Also, the used technique is considered a green method (eco-friendly), as there no organic solvent was used.

Practical implications

The evaluation of the prepared complex pigments as corrosion resistants was also studied.

Originality/value

It is a simple technique, green synthesis (no solvent used) is involved and high yield is obtained.
