P1.3.2 Development of Optical pH Sensor using Conducting Polyaniline -Wrapped Multiwalled Carbon Nanotubes (PANI-MWCNTs) Nanocomposite

&
Highly transparent and water soluble nanocomposite of conducting Polyaniline wrapped - Multi-Walled Carbon Nanotubes (PANI - MWCNTs) was synthesized by an in-situ chemical polymerization method using sulphonic acid as a dopant. MWCNTs were functionalized prior to their use and then polymerized using ammonium per sulphate as an oxidizing agent. The nanocomposite was subjected for physico-chemical characterization using spectroscopic (UV-Vis and FT-IR), FE-SEM and thermal analysis. The UV-Visible spectrum of the salt phase (dark green) of...
