Inkjet Printed Interdigitated Conductivity Cells with Low Cell Constant

Popis výsledku v původním jazyce

A novel approach to the fabrication of gold conductive patterns on alumina, silica, glass and polyimide (Kapton) substrates and physical properties of printed interdigitated cells for measuring electrolyte conductance are reported. The process is based on the direct pattering of a gold resinate dissolved in organic solvent by inkjet printing and firing the prints at 400–800◦C. The resulting interdigitated electrode devices (16 mm x 52 mm exposed area) consisted of 52 to 9 finger pairs of 240 to 1500 μm wide fingers and spaces, respectively. The sheet resistance of the printed Au layers was around 0.27 on alumina (annealed at 800◦C), and 0.86 and 1.18 on glass and Kapton, respectively (annealed at 400◦C). The conductivity cell constants of 0.008 to 0.08 cm-1 of the interdigitated devices were found close to theoretically predicted values. Cells with the lowest cell constants are useful for the measurement of electrolytes of low ionic strength, including ultrapure water. Of the three substrates used, alumina has the advantage of withstanding high temperature curing, whereas Kapton features flexibility, and glass transparency.
