Abstract

SINTESIS DAN KARAKTERISASI POLIPIROL PADA ELEKTRODA KERJA KASA BAJA DENGAN METODE VOLTAMETRI SIKLIK. Telah dilakukan penelitian pelapisan polipirol pada elektroda kerja kasa baja dengan metode elektropolimerisasi pirol secara voltametri siklik.Tujuan penelitian ini merupakan studi awal mempelajari karakter kasa baja yang berpotensi sebagai elektroda kerja tempat elektrodeposisi film polipirol (PPy) berdasarkan literatur. Berdasarkan voltamogram siklik PPy, potensial oksidasi PPy dicapai pada rentang potensial 0V hingga 1V dibandingkan terhadap elektroda pembanding Ag/AgCl pada arus puncak anodik (Ipa) mendekati 7 mA, dengan laju pindai 100 mV/detik dari larutan pirol 0,05 M dalam pelarut KCl 0,1 M sebagai elektrolit pendukung. Pada rentang potensial tersebut selama proses elektropolimerisasi, selain dicapai potensial anodik PPy, terjadi persaingan dengan munculnya potensial anodik dari komponen utama kasa baja yaitu Fe, Zn, Cr atau Mn. Komponen utama yang terdapat dalam kasa baja telah dianalisis dengan X-Ray Fluorescence (XRF). Pelapisan PPy mampu menutupi permukaan kasa baja dengan pertumbuhan polimer sebanyak 10 siklus pada permukaan elektroda dengan mempelajari koefisien korelasi peningkatan arus anodik R = 0,999 dan peningkatan arus katodik R =0,991 terhadap bertambahnya jumlah siklus pada rentang potensial 0,2V hingga 0,8V. Hasil pelapisan film PPy yang menutupi permukaan kasa baja telah dikarakterisasi dengan Fourier Transform Infra Red (FT-IR).

ABSTRACT
SYNTHESISAND CHARACTERIZATION OFPOLYPYROLE ON STEELGAUZE ELECTRODE BY VOLTAMMETRY CYCLIC METHOD. The coating of polypyrrole (PPy)on steel gauze electrode by electropolymerization of pyrrole with voltammetry cyclic method has been investigated. The purpose of this research is a preliminary study the character of a steel gauze as working electrode which potential to electrodeposition on Polypyrrole (PPy) film based on literature. Based on cyclicvoltammogram of PPy, the oxidation potential has been achieved at a potential range of 0V to 1V which compared to Ag/AgCl as reference electrode at a anodic peak current (Ipa) near 7 mA at a scan rate 100 mV/sec from a solution 0.05M of Py in the solution 0.1M of KCl as supporting electrolyte. The competition between PPy with some major component of steel gauze such as Fe, Zn, Cr or Mn occured, in the potential range 0 to 1V during the electropolimerization. The main component of steel gauze has been analyzed by X-Ray Fluoresence (XRF). PPy films can cover the surface of steel gauze with the number of ten cycles of polymer growth on the electrode surface have been studied with the anodic and cathodic peak current with the correlation coefficient 0.999 and 0.991 of the increasing the number of cycles at the potential range of 0.2V to 0.8 V. The results of PPy film on the steelgauze electrode has been characterized by Fourier Transform Infra Red (FT-IR).
