Initial Results

ABSTRACTIonic polymer membrane actuators represent a relatively new and exciting entry into the field of smart materials. Several key limitations of these transducers have prevented them from experiencing widespread use, however. For example, the bandwidth of these devices is limited at very low frequencies by characteristic relaxation and at high frequencies by the low elastic modulus of the polymer. In this paper, an overview of the initial results of work with hybrid ionic / conducting polymer actuators is presented. These hybrid actuators are devices that combine the electromechanical coupling of ionic polymer actuators and conducting polymer actuators into one coupled device. Initial results show that these hybrid devices have the potential to offer marked advantages over traditional ionic polymer membrane transducers, including increased stress and strain generation and higher actuation bandwidth. Details of the preparation of these devices and performance metrics are presented and comparisons to baseline materials are made.

Tip Displacement

Sulfonated endcapped poly (arylenethioethersulfone) copolymer (SPTES) was synthesized through direct copolymerization of sulfonated monomers and poly (vinyl alcohol) (PVA) was crosslinked with SPTES by the dehydration method. The mechanical characteristics of polymer actuators are investigated. Nafion actuators as a comparison were also investigated. The normalized tip displacements were calculated for both PVA/SPTES actuators and Nafion actuators in order to delete the dimensions influence on the bending behaviours. The bending performances were tested under AC excitations with different frequencies. The results showed that the normalized tip displacement decreased with both the width and length of the IPMC strips. That is due to the increase of the monment inetia of the IPMC strips with the increment of the width or the length increment will lead to the larger resistance force from ambient water along with the increase of the area of IPMC strips. PVA/SPTES actuators showed comparable bending performances compared with its Nafion counterparts based on the study of mechanical properties.
