Pengaruh Pencampuran Etilen Glikol dan Propilen Glikol Terhadap Sifat Optik Kawat Nano Perak yang Disintesis Menggunakan Metode Polyol

Research has been carried out aimed for looking effect of mixing Ethylene Glycol (EG) and propylene glycol (PG) on optical characteristics of silver nano wire (AgNWs) which synthesized using the polyol method. Synthesis was carried out for ± 5 hours on temperature of 130 oC inside erlenmeyer flask. The material used are silver (Ag) which is obtained from AgNO3, mixed solution of EG/PG with a concentration ratio of 100:0%; 75:25%; 50:50%; 25:75%; and 0:100%, FeCl3.6H2O, and capping agent in the form of Polyvynil Phyrolidone (PVP). The optical characteristics of AgNWs were observed through UV-Vis, FTIR, and length distribution through optical microscopy. The results of UV-Vis analysis showed four absorption peak at a wavelength of around 340, 350, 360 and at a wavelength of 390 nm as well as a change in the absorbance value. While the optical microscope test results also show that the length of the AgNWs increased on sample EG/PG 75:25% and 50:50%. Based on these results, it can be concluded that the mixing of EG and PG can affect the optical characteristics of AgNWs.
