- Abstract
- New nanostructured conductive porous polymers are prepared by novel atmospheric pressure plasma jets (APPJs) polymerization technique, and their NO2-sensing properties are investigated in this study. This plasma polymerization synthesis technique can grow the poly- and single-crystalline high-density nanoparticles with a fast deposition rate under room-temperature process by improving the sufficient nucleation and recombination of the various monomers, such as aniline and thiophene, using a novel APPJs technique. To check the suitability for sensing materials of gas sensors, the resistance variations of the plasma-polymerized aniline and thiophene nanoparticles grown on the interdigitated electrodes are examined by doping the iodine. As a result, the proposed APPJs device can produce the high density, porous, and ultra-fast polymer films, and polymers based gas sensors have high sensitivities at room temperature.
