Abstract

The role of cation transportation under the effect of an electric field on the actuation of the ionic polymeric- platinum composite artificial muscles is studied. Nafion-117 was platinized by different methods including in situ chemical reduction, physical vapor deposition and electroplating. The strips of membranes platinized by different methods were tested under the effect on an electric field either in the air or water. The extent of the strip bending was correlated with the history of the membrane platinization. Three different mechanisms that could explain the bending of ionic polymeric-platinum composite artificial muscles were reviewed. The history of the membrane platinization together with the extent of bending observed when an electric field was applied identified the electrostatic between the membrane and the platinum particles as the main contributor to the actuation capability in the platinized membrane under the effect of an electric field.
