Nepal Chem. Soc. VL - 42 IS - 1 SE - Research Article DO - 10.3126/jncs.v42i1.35328 UR - https://nepjol.info/index.php/JNCS/article/view/35328 SP - 45-50 AB - <p>Zirconia (ZrO<sub>2</sub>) nanoparticles are polymorphic materials having a wide range of applications. It can be synthesized <em>via</em> green as well as chemical synthesis methods. In this work, ZrO<sub>2</sub> nanoparticles were synthesized by the green method using <em>Curcuma longa</em> extract. <em>Curcuma longa</em> extract was prepared using the standard method. The synthesized ZrO<sub>2</sub> was characterized by the X-ray diffraction (XRD) analysis and Fourier transform infra-red (FTIR) spectroscopy for their structural and size analysis. The analysis of the XRD pattern of ZrO<sub>2</sub> showed the tetragonal phase structure and the size was calculated using the Debye Scherrer equation which was about 34.55 nm. The FTIR spectra analysis showed a broad absorption peak particularly at about 774 cm<sup>-1</sup> and about 499 cm<sup>-1</sup> correspondings to Zr-O<sub>2</sub>-Zr asymmetric and Zr-O stretching modes, respectively. The characterized ZrO<sub>2</sub> nanoparticles were used for the preparation of epoxy resin/ZrO<sub>2 </sub>nanocomposites. The compressive strength of pure epoxy resin and epoxy resin/ZrO<sub>2 </sub>nanocomposites were measured by a compressive strength tester and the result indicates the high amount of zirconia was not suitable for the nanocomposites.</p> ER -
