Industrial Utilizations of Organic Denaturing Clay

Abstract

The organophilic bentonites are organic denaturing clays of montmorillonite of which surface layer is reacted with a quaternary ammonium ion. These types of bentonites, which swell and delaminate in organic solvents, are widely used in many industrial fields. Rheology control like viscosity modifier and antisettling agent are the main usage of this material. Recently the material has also been studied as a functional filler for resins. In this paper, we review the property of organophilic bentonites, their characteristics as a rheology control agent, and disperse-processing methods. We also introduce application to a functional filler for nano-composites as one of a new usage of this material.
