nsf4cIn this work, an electric field was used to assemble a conductive polymer, polyaniline (PANi), onto the patterned template. The employment of electric fields avoids complicated chemistry methods and provides the potential to achieve high throughput and high rates. After assembly, it has been demonstrated that by compression molding or solution casting, patterned PANi can be transferred to polymeric substrates, such as NBR rubber sheet or polyurethane film completely. The conductivity of PANi lines on the PU film was measured as 0.87 S/cm. This simple one-step assembly process for conductive polymers and pattern transfer demonstrates a promising nanomanufacturing approach for high performance flexible nanoelectronics and biosensors.
