Surface functionalization of a-Zirconium phosphate (ZrP) nanoplatelets was achieved by reacting the surface phosphate groups of ZrP with various reactive functional groups. The presence of the modifiers and exclusive functionalization of the surface was confirmed using a combination of X-ray diffraction, FTIR, TGA, XPS, NMR, and electron microprobe. Successful surface modification results in compounds in which the interlayer structure of ZrP is unaltered, allowing for additional chemical reactions to occur in the interlayer region. Combining the well known intercalation chemistry of ZrP with the new surface modification techniques, it is possible to synthesize ZrP nanoparticles with controlled interlayer and surface chemical and physical properties. These designable nanoparticles can be synthesized for specific applications and are expected to improve the applicability of all current ZrP based systems.
