STABILITY OF SILVER BASED CONDUCTIVE FILMS ON CELLULOSE BASED SUBSTRATES

The possibility of integrating printed flexible electronic components into visual solutions that interactively communicate with the consumer represents a new direction in the development of sustainable solutions accessible to all target groups. Flexible electronic thin films are becoming one of the integral elements of visual communication, which means they must be incorporated into the design itself rather than being hidden beneath another element. Today's trends are increasingly directed towards the use of cellulose materials as more acceptable in packaging and other graphic products. In this regard, it was necessary to examine the mechanical, electrical, and colour stability of conductive thin films printed on cellulose substrates. This study examined the possibility of applying conductive silver-based film on cellulose based substrate through the examination of the electric conductivity of silver-based thin films by comparing the quality of prints on two substrates. Additionally, the resistance of printed thin films to double bending and rubbing was investigated. The values of electrical conductivity before and after mechanical testing were compared to explore the potential application of conductive inks in creating visually attractive and mechanically resistant silver-based conductive films. The research has shown that the substrate selection significantly affects the mechanical resistance of prints to bending. Additionally, despite significant visual changes in the conductive thin films, the electrical conductivity of the thin films did not change significantly.
