A Review on Clay Based Hybrid Nano-Pigments Studies
To overcome the common disadvantages of organic and inorganic pigments, a new generation of pigments known as hybrid pigments has been introduced providing advantages of both previous categories and improving some of their disadvantages. These pigments, also known as dye-clay hybrid nano-pigments, are synthesized through an ion-exchange reaction where clay interlayer metallic cations are replaced with dye cations. To understand dye-clay pigments structure, synthesis process and behavior, a deep understanding of clay structure and its behavior in aqueous media is essential. Using this deep understanding further explanation about its synthesis mechanism, thermodynamic, kinetic, effective parameters during the synthesis process and further explanation of their properties is possible and finally, their application in coatings can be studied. These pigments have proved to show good heat and light-fastness as well as good Tinting strength and hiding power in comparison both with the dyes applied in their structure and with commonly used pigments.
