Effect of TiO2 nanoparticles on the electropolymerization of polypyrrole

Catalytic electroxidation pathway for electropolymerization of polypyrrole in solutions containing gold nanoparticles

“…Typically granular raspberry morphology of pure PPy was shown before [17,33]. However, the PPy film in a solution containing Au nanoparticles exhibits a distinguishable stereomorphology, as indicated in Fig.…”

“…As a result, more positively charged PPy, more electron holes available, longer polymer chains and more coplanarity between interchains, are favorable for a higher conductivity performance. The conductivity of oxidized PPy can be increased to a level of 10 3 S cm −1 , or higher, depending on the method of preparation and the doped ion [15][16][17]. Meanwhile, in order to achieve a new function of PPy, one of the most efficient means is to prepare PPy-based composite films into which new chemical components, such as nanoparticles of Fe 2 O 3 and Pd [18,19] or nanostructured clays [20,21], are introduced.…”

Self-aligned TiO2 nanotube arrays produced by air-cathode as electrode

“…Various approaches have been studied and developed to produce nanostructured TiO 2 , the most notable of which include the sol-gel technique [1,2], template-assistant deposition [3], seeded growth [4], hydrothermal processes [5], and metal anodization [6]. Among these techniques, the metal anodization process has been widely regarded as a straight forward surface treatment technique that can be easily automated to produce highly ordered self-aligned TiO 2 nanotube arrays with decent qualities.…”
