Abstract

A hybrid organic-inorganic material composed of barium sulfate (BaSO₄) crystals embedded within a hydrophobic ionic liquid (ILs) matrix has been synthesized. The contact between the inorganic solid and the organic coating is created by chemical interactions between the crystal surface and the ionic liquid. The material exhibits higher affinity to lipophilic media than the non-modified BaSO₄. Increased hydrophobicity is a property often sought for inorganic particles to be applied in non-polar formulations. Immobilization of water-immiscible ILs on a hydrophilic solid carrier enables their application in aqueous solutions and the creation of appreciable hydrophobic-IL/water interfaces on the dispersion of solid-like material in aqueous media.
