In order to provide ultraviolet barrier, antifungal and antibacterial properties, nano-zinc oxide (ZnO) was added to lamellar zirconium phosphate (ZrP). The phosphate was synthesized via reaction of zirconium oxychloride octa-hydrate and phosphoric acid following its chemical modification with Jeffa-mine and nano-ZnO. Diffractometric, morphological, thermal, structural and relaxometric evaluations were conducted. Fourier transform infrared spectroscopy (FTIR) revealed increase of the area between 4000 - 3000 cm −1 due to the formation of ionic specie PO − + NH 3 -[C-(H)(CH 3 )-CH 2 -O-(C-(H)(CH 3 )- CH 2 -O) 8 -(CH 2 -CH 2 -O-CH 3 )] and nano-ZnO particles. Wide-angle X-ray diffraction indicated that intercalation of Jeffamine was successful. Thermogra-vimetry confirmed that nano-ZnO particle forced the expulsion of Jeffamine outside ZrP galleries. Scanning electron microscopy evidenced the Jeffamine intercalation and sample heterogeneity. Hydrogen molecular relaxation indicated the increase of molecular rigidity owing to the formation of ionic specie and the addition of nano-ZnO particles. It was postulated that a multifunctional and miscellaneous material constituted by as prepared ZrP, some de-laminated ZrP platelets and nano-ZnO particles was achieved. The material has potential for usage as filler in polymeric composites.
