Abstract
Conducting polyaniline patterns were deposited on gold, platinum, and carbon surfaces with the use of the scanning electrochemical microscope (SECM). The patterns were deposited in the “micro-reagent” mode in which a local pH change caused by proton reduction at the SECM tip allowed deposition to occur at the substrate. The effect of tip and substrate potential, tip-substrate separation, and deposition time were studied in order to produce well-resolved patterns of the desired thickness. Lateral resolution of the deposited polymer was as low as 3 mm. Conductivity of the film was verified by SECM imaging.
