Finite Element Analysis of Electrochemical-Poroelastic Behaviors of Conducting Polymer (PPy) Films

Computational modeling has been formulated for the electrochemical-poroelastic behaviors of conducting polymers. The three-dimensional continuum modeling based on poroelastic theory for the passive poroelastic behavior of polypyrrole films given by Delia Santa et al. has been extended to the analysis of active electrochemical-poroelastic behavior. The system of governing equations has been established by combining the above modeling with the one-dimensional ionic transportation equations given by Tadokoro et al. The established equations have been discretized by the finite element method. The validity of the proposed computational modeling has been illustrated by comparing the calculated solutions for the passive and active behaviors of polypyrrole films with the theoretical and experimental results.
