Surface Modification of MWCNTs: Preparation, Characterization and Electrical Percolation Studies of MWCNTs/PVP Composite Films for Realization of Ammonia Gas Sensor Operable at Room Temperature
MWCNTs produced by using Chemical Vapor Deposition (CVD) technique were oxidized using liquid phase oxidation method where, MWCNTs were treated with mixture of Sulphuric and Nitric acid (3:1).The FTIR analysis further confirmed the presence of functional groups on the surface of MWCNTs after chemica...
