Abstrakt
In the recent time, the printing of functional substances (e.g., conducting
polymers, metal-particle composites, carbon black and graphene based materials,
etc.) has become of large importance. The main reason is the establishment of
so-called printed electronics, where such substances are applied and later form
functional electronic devices (e.g., sensors, displays, photovoltaic cells,
transistors, etc.). Polyaniline has been reported to be a very versatile conducting
polymer. Therefore, its application in a formof functional coatings and thin layers
is desired. Polyaniline can be prepared in the presence of water-soluble polymeric
stabilizers [e.g., poly(N-vinylpyrrolidone)], so that stable colloidal dispersions
are obtained after the synthesis based on the oxidation of aniline with ammonium
peroxydisulfate. These dispersions must be further adjusted for the needs of
printing. This work is focused on the application of polyaniline-based dispersions by means of screen-printing method. A screen-printable formulation of
polyaniline-based dispersion was prepared and printed on Melinex® ST504
poly(ethylene terephthalate) substrate. The quality and functionality of the
prepared layers was studied by means of common methods (electrical resistance
measurement, profilometry, optical microscopy with image analysis, optical
spectroscopy). The prepared polyaniline films were examined also by means of
photoacoustics, where changes in the subsurface structure and thickness of the
polyaniline layers could be observed. The influence of the printing parameters as
well as the components of the prepared formulations on the resulting quality and
functionality was investigated.
