Abstract

Poly(N-ethylaniline) (PNEA) and poly(aniline-co-N-ethylaniline) (co-PNEA) films have been synthesized on a pencil graphite electrode (PGE) by using cyclic voltammetry (CV) in an acetonitrile (ACN) solution of tetraethylammonium tetrafluoroborate (TEABF4). The electrochemical properties of the electrodeposited coatings have been characterized using CV method in monomer free solution. The surface morphologies of the films have been investigated by Scanning Electron Microscope (SEM). The electrochemical storage properties of polymer coated PGE (PGE/PNEA and PGE/co-PNEA) have been evaluated by CV, electrochemical impedance spectroscopy (EIS), galvanostatic charge-discharge and repeating chronopotentiometry tests. The highest specific capacitance values of PGE/PNEA and PGE/co-PNEA have obtained as 1112.72 mF g-1 and 1830.00 mF g-1 at 0.01 mA by using galvanostatic charge-discharge, respectively. According to repeating chronopotentiometry tests, it is observed that charge-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 PGE’ların (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-1PGE/PNEA’un PGE/co-PNEA’tan daha yüksek şarj-deşarj kararlılığına sahip olduğu gözlenmiştir.olarak elde edilmiştir. Tekrarlanan kronopotansiyometri yöntemine göre
