Abstract

The copper selenide (Cu2Se)/polyaniline (PANI) nanocomposite was synthesized successfully by in situ
polymerization through a simple and harmless technique. The structural characterization was carried out using
Brucker D2 phase XRD. The optical measurements were made from UV-Visible spectrometer at normal
incidence light wavelength in the range of 330-1100nm. Fourier transform infrared (FTIR) spectrograph
confirmed the presence of functional groups and also the interaction between the polymer chains and Cu2Se
nanoparticles. The characteristic peaks in FT-IR and UV-Visible spectra were found shifted to higher wave
numbers, which is attributed to the above said interaction. XRD pattern revealed the orderly arrangement of the
polymer composite. Results obtained supports the prepared nanocomposite may be used as a multifunctional
material for different nanoelectronic devices.
