Abstract
The conductive polymer polyaniline PANI has various useful functions such as redox activity color and conductivity changes depending on the oxidized state reversible anion doping/dedoping and acid/base equilibria 1 2 3 Some of the functions have already been utilized in devices such as lightweight secondary batteries electrochromic displays electromagnetic shielding devices and anticorrosion coatings It has also been investigated for other practical uses 1 2 3 There is no doubt that the morphology control of PANI in particular the control of the micro and nanostructures is a significant factor not only its the utilization but also for the addition of new significant functions For example the nanofibrillar morphology improves the performance of PANI in most conventional applications involving polymer interactions with its environment 4 This leads to much faster and more responsive chemical sensors new inorganicPANI nanocomposites and ultrafast
