Conducting IPN Fibers: A New Design for Linear Actuation in Open Air
In this work, we report the development of “one piece” electrochemical actuator fibers, presenting linear deformations, and working in open-air. The hollow fiber shaped actuators are synthesized as three components Interpenetrating Polymer Network (IPN). The electronic conducting polymer (ECP), poly(3,4-ethylenedioxythiophene) (PEDOT), is embedded in a hollow fiber shape matrix working as two ECP concentric electrodes. The host matrix which presents an IPN type architecture is composed of two poly(ethylene oxide) networks, crosslinked in the presence of each other. Strains up to 3 % and forces between 50 and 300 mN are realized in a two electrodes configuration, in open-air.
