  • Title: Single-Walled Carbon Nanotubes Decorated with Polypyrrole-TiO2 Nanocomposites.
    Author: Radha G, Samanta D, Balakumar S, Mandal AB, Jaisankar SN.
    Journal: J Nanosci Nanotechnol; 2015 May; 15(5):3879-86. PubMed ID: 26505018.
    Abstract:
    Nanomaterials decorated with polypyrrole were synthesized using two types of oxidants by chemical oxidative polymerization method. The interaction and influence of the addition of single-walled carbon nanotubes (SWCNTs) and titanium dioxide (TiO2) nanoparticles in polypyrrole (PPy) were studied using Fourier transform infrared spectroscopy and Raman spectroscopy. Thermal stability has been observed by using thermogravimetric analysis. Electrochemical properties were calculated by using Cyclic Voltammetry to study comparative analysis between samples. Particle size measurements and morphology were determined by Field emission transmission electron microscopy. All the nanocomposites exhibit better thermal and electrochemical properties than native polymer. The size of the polypyrrole particles were in the range of 50 nm to 60 nm.
