Effect of mechanical mixing method of preparation of polyaniline-transition metal oxide composites on DC conductivity and humidity sensing response

In the present work, optimized polyaniline-titanium dioxide (PANI-TiO2) and polyaniline-yttrium oxide (PANI-Y2O3) composites were prepared by mechanical mixing of chemically synthesized PANI with TiO2 and Y2O3 transition metal oxides respectively. The Fourier transform infrared spectroscopy (FTIR) analysis confirmed relative decrease in depth of delocalization band of PANI in the composites as compared to that in PANI. The X-ray diffraction...
