Conducting polymer PPy nanowire-based triboelectric nanogenerator and its application for self-powered electrochemical cathodic protection

Abstract

A novel triboelectric nanogenerator (TENG) was constructed with PPy nanowires (PPy NWs). By harvesting the energies in the ambient environment, the PPy NW-based TENG can act as a power supplier and provide extra electrons to the surface of the connected metals, forming effective impressed current cathodic protection.

Polypyrrole Nanofibers with Extended 1D Hierarchical Structure

“…Polypyrrole nanofibers deposited on titanium(IV) oxide or combined with silver nanoparticles have been examined as photoanode materials. Polymer nanofibers have also been used for controlled drug release,, for water deionization, and in triboelectric nanogenerators (TENG) …”

Recent progress on nanostructured conducting polymers and composites: synthesis, application and future aspects

“…The morphology of grown NCPs can be influenced by several factors such as diffusion and reaction kinetics, interaction between wall of the pores and polymer at higher oxidation potential. The controlled synthetic technique for nanowires/tubes made it feasible to investigate the performances of electrical devices [49]. However, size and pore density of the solid template challenged to produce the NCPs in large-scale using this method.…”

“…The diameters of PTMs pores can be as small as 10 nm and the density of pores ranges from 10 5 to 10 9 pores per cm 2 [40]. Many NCPs such as PANI [45,47], PPy [48,49], PEDOT [50,51], have been chemically or electrochemically synthesized in the form of nanowires or nanotubes by different membranes. As shown in Fig.…”

“…The device can power a digital temperaturehumidity meter and can power as many as 40 reactors. Cui et al [49] proposed a novel TENG constructed with PPy nanowires prepared by an electrochemical polymerization method using AAO as a template. The synthesized PPy based TENG showed excellent durability and high output performance with a short circuit current density of 23.4 mA m −2 and output voltage of 351 V. The smart device can be used to power a cathodic protection system to protect metals from corrosion.…”

“…In Fig. 3b, PPy nanowirebased triboelectric nanogenerators were synthesized by using electrochemical polymerization method with AAO as template [49]. The Ti substrate was used as electrode and fixed with the AAO template.…”
