Title:

NANOPLATELET-TYPE ZIRCONIUM PHOSPHATE AND METHOD FOR PREPARING SAME

Document Type and Number:

WIPO Patent Application WO/2012/091426

Kind Code:

A2

Abstract:

The present invention relates to a platelet-type zirconium phosphate which has a P-OH group in the structure thereof, has a crystalline peak at a 2è value of 11.6±2 degrees in an X-ray diffraction analysis, and shows no crystalline peak at a 2è value of less than 11.6±2 degrees. The platelet-type zirconium phosphates prepared by the method of the present invention have a platelet structure and may be uniformly dispersed at the nanoscale in a film to exhibit excellent surface gloss and barrier capability. The platelet-type zirconium phosphates prepared by the method of the present invention have the P-OH group at the surface thereof so as to exhibit excellent corrosion resistance, and may be dispersible not only in an aqueous solution, but also in an organic solvent or the like.
