In this study, we aim to introduce a nanoscale patterning strategy for transparent and highly sensitive sensors using colloidal lithography and vapor phase polymerization. We use monolayer of PS colloidal crystal as a template to create FTS nano-patterns on the substrate. Then, two- dimensional honeycomb-structured porous poly(3,4-ethylenedioxythiophene) (PEDOT) nano-patterns are formed through vapor phase polymerization. The patterned substrate exhibits higher transparency due to the presence of voids. It is also demonstrated that in bending test, the honeycomb patterned substrate exhibited greater resistance changes compared to the unpatterned substrate. This is attributed to the fact that the patterned substrate experiences more stress concentrated on the narrow patterned area, resulting in higher sensor sensitivity than the unpatterned substrate. This fabrication method provide effective route for the fabrication of various of nano patterend conducting polymers which can be applied in optical/ electical/ sensing devices.
