Gel-layer-assisted directional electropolymerization: A versatile method for high-resolution volume and surface patterning of flexible substrates with conjugated polymers

The versatility and high performance of a new directional electropolymerization (DEP) process with a resolution of less than tem micrometers, which allows volume or surface micropatterning of flexible polycarbonate membranes with conjugated polymers, was discussed. The DEP process holds great promise for potential applications in 3D chip stacking and all-plastic electronics. Conductivity and cross-talk measurements of the polymer volume micropatterns were carried out with a specially constructed test rig. It was concluded that the tailored monomers could be used to generate micrometer-sized conductive deposits endowed with specific functions for the generation of flexible sensor devices.
