Optimizing Electrochemical Microprinting of Conducting Polymers: Scanning Electrochemical Cell Microscopy (SECCM) Coupled with Conveyor-Belt Surface Analysis.

ABSTRACT: Scanning electrochemical cell microscopy (SECCM) is a versatile tool for localized electrochemical mapping, material modification, and microfabrication. In its hopping mode, the pipette-based system confines reactions to the meniscus contact area, allowing precise deposition control. Here, an SECCM-driven strategy for polypyrrole (PPy) microfabrication using phosphate buffer as the electrolyte, combined with an intermediate cleaning step to remove side products and prevent pipette clogging, is reported. This approach enables the production of uniform, circular PPy deposits with high reproducibility on gold substrates. A multi-microscopy "conveyor-belt" analysis - combining SEM, AFM, EDX, and Raman spectroscopy - reveals that phosphate ions intercalate into the PPy matrix during polymerizat
