A simple method is developed to produce free-standing films of polypyrrole (PPy) in one step. It consists the interfacial polymerization (without surfactants) pyrrole (dissolved chloroform) with an oxidant (ammonium persulfate, dissolved water). observed that area formed film only depends on size interface, achieving manufacture PPy up 300 cm2, a thickness 200 microns. Transmission electron microscopy (TEM) images show presence superimposed nanoplatelets ca. 100 nm main axis. These nanoparticles seem aggregate two dimensions form film. Scanning (SEM) shows compact surface nanowires decorating surface. electrical conductivity 63 (±3) S cm−1. conductive are then applied construction antenna response bands: at 1.52 GHz (−13.85 dB) and 3.50 (−33.55 dB). The values comparable those other antennas built different films. synthesis large-area single step would allow fabrication large quantities electronic elements (e.g., sensors) uniform properties short time.
