Atmospheric Pressure Plasma Polymerization of In Situ Doped Polypyrrole

The conjugated polymer polypyrrole can be useful in a lot of applications such as LEDs, solar cells, organic thin film transistors, (bio)sensors, corrosion protection and antistatic layers.However, today, large area coating is still difficult.For this reason, plasma deposition at atmospheric pressure is presented as an alternative synthesis method, because of its possibility for inline processing and in situ doping.Furthermore, plasma polymerization is a more environmental friendly dry technique.Injection of a pyrrole aerosol into a nitrogen plasma and in situ doping by coinjection of NOBF4 or iodine, results in polymerization and coating deposition.The so formed coatings are analyzed with XPS, FTIR, UV/VIS, and resistance measurements.Conductivities up to 10 -3 S/cm were reached.
