Abstract

Poly(N-ethylaniline) (PNEA) and poly(aniline-co-N-ethylaniline) (co-PNEA) films have beensynthesized on a pencil graphite electrode (PGE) by using cyclic voltammetry (CV) in an acetonitrile(ACN) solution of tetraethylammonium tetrafluoroborate (TEABF4 ). The electrochemical properties ofthe electrodeposited coatings have been characterized using CV method in monomer free solution. Thesurface morphologies of the films have been investigated by Scanning Electron Microscope (SEM). Theelectrochemical storage properties of polymer coated PGE (PGE/PNEA and PGE/co-PNEA) have beenevaluated by CV, electrochemical impedance spectroscopy (EIS), galvanostatic charge-discharge andrepeating chronopotentiometry tests. The highest specific capacitance values of PGE/PNEA andPGE/co-PNEA have obtained as 1112.72 mF g-1 and 1830.00 mF g-1 at 0.01 mA by using galvanostaticcharge-discharge, respectively. According to repeating chronopotentiometry tests, it is observed thatcharge-discharge stability of PGE/PNEA is longer than PGE/co-PNEA.

Özet

Poli(N-etilanilin) (PNEA) ve poli(anilin-ko-N-etilanilin) filmleri 0.1 M tetraetilamonyumtetrafloroborat (TEABF4 ) içeren asetonitril (ACN) çözeltisi kullanılarak dönüşümlü voltametri (CV)yöntemiyle kalem grafit elektrot (PGE) yüzeyinde sentezlenmiştir. Elde edilen filmlerin elektrokimyasalkarakterizasyonu monomersiz çözeltiler içerisinde CV yöntemi kullanılarak gerçekleştirilmiştir.Filmlerin yüzey morfolojileri taramalı elektron mikroskobu (SEM) ile görüntülenmiştir. Polimer filmikaplı PGEların (PGE/PNEA ve PGE/co-PNEA) elektrokimyasal enerji depolama özellikleri CV,elektrokimyasal empedans spektroskopisi (EIS), galvanostatik şarj-deşarj ve tekrarlanankronopotansiyometri yöntemleriyle araştırılmıştır. PGE/PNEA ve PGE/co-PNEA için en yüksekspesifik kapasitans değerleri galvanostatik şarj-deşarj yöntemi ile 0.01 mA akımda sırasıyla 1112.72 and1830.00 mF g-1 olarak elde edilmiştir. Tekrarlanan kronopotansiyometri yöntemine göre,PGE/PNEAun PGE/co-PNEAtan daha yüksek şarj-deşarj kararlılığına sahip olduğu gözlenmiştir.
