Title Preparation and research of polyaniline - tungsten oxide - titanium oxide nano composite electrode
Abstract
This dissertation was prepared polyaniline - tungsten oxide - titania nanocomposite electrode,
and were tested for its electrochemical performance in different environments .We explores the
voltage, current and other factors impact on the morphology of titania nanotubes. We also focus
on how the titania nanotubes, which generated in different conditions, impact on tungsten oxide
deposition. The main work is as follows:
The preparation of titania nanotubes is studied mainly though method of constant voltage
oxidation, and by changing the oxidation voltage values to change the morphology of the
nanotubes. By scanning electron microscope (SEM), we can observe the surface and
cross-section of nanotubes arrays to analysis the morphology of the different films, which can
help us obtain the relationship of voltage and nanotube diameter and length.
The nanotube arrays made under suitable conditions was used for the deposition of tungsten
oxide and to study the impact of voltage and time on deposition by changing the deposition
voltage and deposition time. Through experiments we have found the best deposition conditions
and further obtained the new composite electrode materials.
Keywords titania polyaniline(PINI) supercapacitor anodization
