Gas sensing of colloidal polyaniline in a chemoresistor consisting of nanometer electrodes

Synthesis and Characterization of Polyaniline Copolymer

“…(PANI) is one of the most studied electrically conducting polymers because of its easy preparation, chemical stability, unique proton dupability and a good electrical conductivity (≈100S cm -1 ) [1], PANI with a conjugated π-bond system makes it an important and unique number in the family of conducting polymers. It found its own applications in optical and electrochromic devices [2], photoelectric cell [3,4], electromagnetic shielding [5], light-emitting diodes [6,7], corrosion protection [8,9,10], sensors and microelectronic devices [11,12] ,smart window [13]. Usually there are two main manners to obtain PANI, one is chemical oxidative polymerization, the other is electrochemical polymerization.…”
