The synthesis of conductive composite using pretreated lignin was performed in the form of lignosulfonates(LGS) to imitated PEDOT:PSS. Solubility of LGS was verified and synthesized PEDOT:LGS composite was characterized by fourier transform infrared and BET surface area measurement. The composite synthetic condition is presented synthetic requirements by electrochemical measurements. Na2S2O8 plays a role as reaction initiator, indicating that it must be added for composite synthesis. In PEDOT:LGS ratio, the electrical performance was shown to be conformable performance near the 1:1 ratio. In neutral sulfonation Na2SO3 addition variables, at certain condition electrical performance trends had decreased. It is analyzed that the SO32- ions produced by Na2SO3 form the matrix of conductive composite and SO32- remaining ions decrease the electrical performance of the composite. |
