FABRICATION OF SILVER NANOPARTICLES IN POMEGRANATE SEED OIL WITH THERMAL PROPERTIES BY LASER ABLATION TECHNIQUE

Silver nanoparticles were fabricated in pomegranate seed oil using laser ablation technique. A silver plate was ablated for 5 minutes, 10 minutes, 15 minutes and 20 minutes using Nd: YAG Q-Switched laser to prepare the nanofluid. The nanofluids were characterized using UV-visible, transmission electron microscopy and Fourier transform infrared spectroscopy, respectively. The silver nanoparticles were formed in spherical shape and particles size shifted from 21 to 2 nm with increasing the ablation time. The silver nanoparticles were capped by carboxylic groups (-COO-) of the pomegranate seed oil. Moreover, the thermal effusivity of samples was measured using the photo-acoustic technique, and the thermal effusivity shifted from 0.095 Ws(1/2)cm(-2) K-1 to 0.144 Ws(1/2)cm(2)K(-1) that confirmed the silver nanoparticles enhanced the thermal properties of pomegranate seed oil. Consequently, the laser ablation techniques succeed to fabricate the silver nanoparticles in the pomegranate seed oil.
