In this research we utilize polyaniline nanofibers in security printing applications. Polyaniline nanofibers were synthesized to allow an aqueous-based ink to be created. Inks with different weight percentages of polyaniline nanofibers were formulated, printed into desired patterns on a variety of substrates using digital fabrication and characterized for their conductive properties. The conductivity differences between the flash welded regions and non-flash welded regions were determined to help determine applicability for security-end products.
