New nanofluids containing Ag nanowire with different concentrations were prepared by
chemical reduction method. The metallic nanowire are monodispersed and soluble in water.
Thermal diffusivity of nanofluids containing Ag nanowires were measured by Thermal Wave
Resonator Cavity technique [1] in order to measure the effect of the presence of nanowire on
the nanofluids thermal diffusivity. The thermal diffusivity of the nanofluids seems to be
strongly dependent of Ag nanowire concentration. It was observe an increase of thermal
parameters when concentration of nanowire increases. Thermal diffusivity behavior of the
nanofluids is explained. Also, UV-Vis spectroscopy, SEM microscopy, EDS and XRD
techniques were used to characterize the nanofluids.

In Figure 1 the UV-vis absorption spectra of Ag nanowires for the different concentrations
can be seen. On the other hand, lineal changes for the absorption of Ag nanowires as a
function of different concentrations are observed in Figure 2.
