Abstract:
Conductive polymers, with their unique mechanical flexibility, electrical conductivity, and optoelectronic properties, have shown great potential in various fields. However, 3D patterning of conductive polymers has been limited by resolution, material compatibility, and structural complexity. In this study, these challenges were addressed by fabricating three-dimensional (3D) Ag/PEDOT, Ag/PTH, and Ag/PPY structures with a resolution of 600 nm inside nanoporous silica gel glass using femtosecond laser direct writing (FsLDW) technology. Notably, these microstructures can effectively amplify the Raman signals of organic dyes. This study introduces a new strategy for 3D patterning of conductive polymers, opening up new avenues for applications in flexible electronics and sensing.
