Transparent Conductive Printable Meshes Based on Percolation Patterns (original) (raw)

2019, ACS Applied Electronic Materials

Transparent conductive meshes were fabricated by ink-jet printing on flexible substrates using a percolation pattern created by random removal of conducting bonds from a regular square two-dimensional lattice. With this approach, a higher gain in optical transmittance than electrical conductivity loss is achieved above the percolation threshold. As a result of this, a figure of merit for the percolation pattern is improved with respect to a regular square mesh. The transmittance (T), sheet resistance (R), and figure of merit (F) on percentage of removed bonds for square lattices printed were measured. The gain of the figure of merit was observed in the range of removed bonds from 5% to 15% .
