Abstract

The optimum processing conditions for PEDOT:PSS and PEDOT:PSS/Tween 80 cast films have been investigated in terms of film quality and resistivity. The thermal stability of these materials has been found to strongly influence the annealing temperatures that can be utilised, especially in the presence of the conductivity enhancing agent, Tween 80. The resistivity of PEDOT:PSS films with and without Tween 80 was found to decrease by up to 85% with both annealing temperature and time until a plateau is reached. In addition, thermal structural rearrangement of the polymers has been established as the key driving factor that reduces resistivity, with water removal alone being insufficient. Finally, the optimum processing conditions for PEDOT:PSS and PEDOT:PSS/Tween 80 films are detailed.
