Organic Electrical Passive Components Based on Polyaniline

Polyaniline (PANI) is a valuable, old, complex, organic, nontoxic, cheap, semiflexible, good environmental properties (electrical conductivity value of 10_10 to 10_5 S cm_1), conducting polymer material having interesting properties (and having a huge potential to be applied in industry (especially in microelectronics), beeing among the most studied conducting polymer during the last 50 years.Polyaniline has interesting properties: it has both electronic and ionic conduction, a color changing is observed depending on the degree of its oxidation/reduction state, it has a high chemical and thermal stability, presents piezoresistive properties, and has cytocompatibility. Many of these properties can be controlled by doping/dedoping phenomena. With these remarkable properties, polyaniline is a valuable candidate for large-scale industrial applications, including passive electronic components manufacturing (resistors and capacitors).
