ABSTRACT
Hydrophilicity and hydrophobicity of pottery bodies can be controlled via chemical substitution of layered clay with hydrophilic and hydrophobic organics. In this study, organo-clay nanocomposites were prepared by ion-exchange of montmorillonite with dodecylamine and hexadecylamine, respectively. Substitution sites of organics and the interval changes of layered materials are characterized by FT-IR and WAXD and organics amounts loaded and water comtents contained by C/S analysis and TG-DSC. The organics were selectively intercalated so that increase layer interval from 12${AA}; to;16{AA}$. Organo-modified clay is changed to more hydrophobic comparing to clay itself.
Key words: Clay, Modification, Organics, Montmorillonite, Dodecylamine, Hexadecylamine
