SUMMARY:Electrochemo-poromechanical interactions: the case of ionic polyme
 r metal composites - Alessandro Leronni\, CUED

CONTACT:Hilde Hambro
DESCRIPTION:In this talk I present a thermodynamically consistent large de
 formation theory coupling electrostatics\, ion and fluid transport\, and m
 echanics. The mechanical stress\, electrostatic stress\, and fluid pressur
 e contribute to the total stress. The total fluid flux results from the fl
 uid pressure gradient and the electro-osmosis with mobile ions. The total 
 ion flux is given by diffusion in a deformable body\, migration in the ele
 ctric field\, and convection with the fluid. The proposed theory finds app
 lication in the study of porous materials saturated with a solution of flu
 id and ions. Here\, I examine the case of ionic polymer metal composites\,
  a class of electroactive polymers finding application as actuators and se
 nsors.
