RELIABILITY PERFORMANCE OF GNP/Ag/SA HYBRIDIZATION STRETCHABLE CONDUCTIVE INK ON CYCLIC BENDING

Abstract

In this rapidly changing era, new needs and demands for electronic products, particularly flexible electronics, necessitate ever-superior qualities, particularly in terms of flexible and stretchable devices. As a result, the goal of this research is to look into the behaviour of GNP hybrid-based conductive ink when subjected to cyclic bending, which can explain the material's flexibility performance. Sample made with hybrid GNPs and organic solvents. The ink was printed on a single crystal copper (Cu) substrate with two different samples in terms of average graphene size, 5 μm and 25 μm, at three distinct points. The lowest sample with the highest resistance or conductivity was tested using conductive ink characterisation. The electrical performance under cyclic bending conditions shows that the lower the resistivity value, the smaller the average particle size of the hybrid GNP particles. This study's overall findings provide a deeper insight, particularly in terms of selecting acceptable conductive ink qualities that can endure recurrent bending fatigue. Substrate flexibility and bending resistance performance are significant aspects for obtaining optimal electrical and to reduce strain on the ink during bending, resulting in better ink electrical conductivity retention.
