Abstract
  • Conductive ink is used as interconnecting tracks to create conductive paths. This research main objective is to utilised composite materials for conductive ink which to enhanced the production of making conductive ink which has good engineering properties in terms of electrical conductivity and cleaner productions. Thermoplastics viscous paste used as conductive materials to enlarge the capability of conductive ink to conducts electricity. The conductive ink applications offer many opportunities of carbon nanomaterial purposely for printed, stretchable and flexible electronics. Graphene nanoparticles conductive ink used as the connection material, fabricated on thermoplastic polyurethane (TPU) using manual stencil method for straight line, curve, square and zigzag pattern to investigate the effect of sheet resistivity for all the pattern state above. The samples used fix circuit width of 1mm, 2mm and 3mm. The ASTM F390 four-point probe used to measure the values of sheet resistivity. Results of this study displayed that 1 mm width samples provided the lowest value of sheet resistivity while, the higher values was displayed by 2 mm width samples nearly all the patterns.
