Conductive polymer is insulator or semiconductor in initial state. Polyaniline(PANI) is a $\pi$-conjugated polymer that shows electric property changes, when it is contact with oxidant/reductor chemicals. Synthesis of polyaniline is used vacuum evaporation method, using by (NH$_4$)$_2$O$_{8}$과 NMP, NH$_2$NH$_2$, HCl, MH$_4$OH, etc. Doped PANI is used such a resistor, addition to graphite is increased conductivity. Applying contact voltage, samples show constant current and contact temperature.e.
