Thermal management of Ionic Polymer-Metal Composites

The main objective of the current research work is to evaluate 2-D transient temperature distribution in an Ionic Polymer-Metal Composite (IPMC). Most of the prior work on IPMC concentrated on its ability as actuators and sensors. The effect of temperature distribution due to applied voltage in an IPMC composite has not been studied earlier and is the main subject of the current research. In determining the temperature distribution in IPMC, FEMLAB 3.1 software was used for modeling purpose. In developing the model the IPMC is assumed to be at room temperature. In developing the model platinum and Nafion are assumed to be in perfect thermal contact. The data obtained form the model showed that a maximum temperature rise was seen at the regions where the heat flux was applied (near the electrode) and the rest of the IPMC has shown no significant rise in temperature. This may be attributed to Nafion's very poor thermal conductivity and very high specific heat capacity.
