nanoparticle metal oxide materials for conductive and
dielectric screen printing inks were investigated. Screen
printed parallel plate capacitors were fabricated to research
the applications of these inks. Conductive, micron-particle
indium tin oxide (ITO) screen printing inks were formulated
for the conductive plates. A dielectric, nanoparticle aluminium
oxide (Al2O3) ink was formulated for the dielectric barrier.
Capacitors of varying sizes (1cm2 – 9cm2
) were printed onto
flexible polyethylene terephthalate (PET) sheets. The effect of
dielectric layer thickness was investigated to find the optimal
fabrication process. Impedance analysis was performed on the
capacitors to characterise both the performance of the
capacitors and the dielectric ink. Analysis of the capacitors was
also performed under flex (up to 30% strain) to investigate the
effect of bending on the electronic properties. The capacitors
were found to be highly stable under bending enabling their
use in flexible printed electronics applications.
Funding
The research was funded as part of the EPSRC grant (EP/L017709/1) for research into “Sustainable Manufacturing of Transparent Conducting Oxide (TCO) Inks and Thin Films” .
