T he electroactive polyaniline at high pH was electrochemically synthesized in a solution containing 0.2 mol.dm-3 aniline and ionic liquid, 1-ethyl-3-methylimida-zohum-ethyl sulphate (EMIES). The cyclic voltammograms of the polyaniline were performed in 1.0 mol.dm-3 KCI in a range of pH from 8.0 to 12.0 between 0 0 and IrtJfv J° "In The,?sults indicated onlV 144% decay of the electrochemical activity when the polyaniline was moved from pH 8.0 to 10.0. The polyaniline still retains good electrochemical activity at pH 12.0. The results of UV-visible and FTIR spectrum reveal that the framework of polyaniline synthesized in EMIES is similar to Sl? p°יy<^nehSynthesized in HCL The dermal behaviour of the polyaniline pre- , S Sh°WS a three"steP weי9ht loss process, they are at about 100°C 200-EMIEst nmTf °O
