Seed-free synthesis of 1D silver nanowires ink using clove oil (Syzygium Aromaticum) at room temperature

Abstract

HypothesisSilver nanowires (AgNWs) have been demonstrated to be a promising next generation conducting material and an alternative to the traditional electrode (ITO) because of its high conductivity, transparency and stability. Generally, AgNWs are synthesized by chemical method (mainly polyol reduction method) at high temperature in the presence of exotic seeds. The present work aims at the green approach for preparation and characterization of 1D AgNWs ink using clove oil (Syzygium Aromaticum) at room temperature. ExperimentsAgNWs was prepared by green synthesis using clove oil as reducing as well as capping agent at room temperature. The obtained ink was purified, filtered and redissolved in methanol. FindingsThe prepared AgNWs showed an absorption peaks at 350 and 387nm in the UV–vis spectrum due to transverse SPR mode of silver. From the HR-TEM analysis, it was observed that the AgNWs possess an average diameter and length of ∼39±0.01nm and ∼3μm, respectively. The obtained AgNWs are crystalline in nature and are arranged in a perfect crystal lattice orientation, which was confirmed from the selected area electron diffraction studies. Moreover, the X-ray diffraction analysis confirms the face centered cubic structure. The AgNWs coated glass substrate shows an electrical conductivity of ∼0.48×106S/m.
