Green synthesis and spectroscopic studies of some complexes compounds as pigments and their applications in paints

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.
