Elektrosintesis konduktor P-polyanalina dengan anoda karbon.

Abstract

Telah diteliti, reaksi elektrosintesis senyawa anilina dengan perpaduan elektrolit pendukung asam klorida (HC1) 1,5 M, anoda karbon dirotasikan, rentang voltase 1,1 - 1,4 volt dan kuat arus 10 - 50 mA, menghasilkan produk polimer konduktor dengan daya hantar 2,54 x 10-2 titik didih 5000C, dan sifat padatan rapuh berwarna hijau. Berdasarkan spektrum Infra Merah dan Ultra Ungu, maka disimpulkan bahwa produk elektrosintesis identik dengan struktur molekul p-polyanilina. Pengendalian atas perilaku unik elektron dan fenomena antarmuka elektroda yang meliputi : perpindahan massy (migrasi ion, difusi dan konveksi), adsorpsi-desorpsi dan transfer elektron menjadikan elektrosintesis sebagai metoda yang cukup efektif dalam mengatasi kerumitan mekanisme reaksi, khususnya pada sintesis polimer konduktor yaitu p-polyanilina. It'has been examined, that electrosynthesis reaction of aniline with combination of supporting electrolyte, hidroohloride acid 1,5 II, rotated carbon anoda, with interval voltage 1,1 - 1,4 volt and current 10 - 50 mA, produced conducting polymer. The characteristics solid is brittle, green colour, boiling point 500°C, and electronic conductivity about 2,54 x 102 cm-johm-1. Based on infrared and ultraviolet spectrum, it were concluded that electrosynthesis product is identic with p-polyaniline molecule structure. With controlling unique behavior of electron and electrode interfacial phenomena,including of mass transport ( ionic migration, diffusion and convection ), adsorption -desorption and electron transfer, cause electrosynthesis as a quite effective methode to surpass difficulties mechanism reaction, especially to synthesis conducting polymer, that is p-polyaniline.
