• . TENGs can also be used to harvest mechanical energy and drive electropolymerization processes without an external power source to drive the electrochemical reaction. Shi et al. obtained a P-TENG electrochemical system for electropolymerizing polyaniline (PANI) on a CNT electrode. Figure 10a shows the

• schematic illustration of a TENG electrochemical system (including a TENG, a rectifier and a capacitor), which was used to improve the capacitance of the CNT electrode by PANI electropolymerization [162]. The TENG powering component was comprised of a cellulose/BaTiO3 aerogel paper as the positive friction

• layer and PDMS as the negative friction layer. The modified CNTs embedded into a thin layer of PANI by the TENG electrochemical system showed a larger diameter compared with the pristine CNTs, as shown in Figure 10b. The electropolymerization of PANI on a CNT electrode is also identified by the Raman

The PGA/MWCNT/GCE was fabricated by potentiostatic electropolymerization of gallic acid on the MWCNT/GC electrode by applying an anodic potential of 1.0 V vs Ag/AgCl for 60 s. The prepared electrode was washed several

These monomers differ by the length (C4F9, C6F13 and C8F17) and the position (4-, 5- and 6-position of indole) of the perfluorinated substituent. Polymeric films were obtained with

The last

Also, the short length of the new oligomers formed during the electropolymerization process increases their solubility
