- Abstract
- Graphene is a two dimensional material with extremely favorable sensing properties. In the present work we proposed the use of graphene films for the conductivity measurements of ionic liquids. Recently ionic liquids have attracted enormous attention for green synthesis and their applications in fuel cells, solar cells and batteries. Here we show the feasibility to use graphene films for measurement of ionic conduction in ionic liquids at room temperature for the first time. The graphene film is deposited on silicon substrate having 1mm electrode gap. A micro liter drop of analyte was placed on the graphene film. The preliminary results for used analyte such as Sodium Chloride (NaCl), Ammonium Chloride (NH(4)Cl) and Ammonium Sulphate ((NH(4))(2)SO(4)) for same molar concentration are encouraging and shows distinct variation in ionic conduction.
