Thin film free-standing PEDOT:PSS/SU8 bilayer microactuators

Abstract: Abstract. Several smart active materials have been proposed and tested for the development of microactuators. Among these, conjugated polymers are of great interest because miniaturization improves their electrochemical properties such as increasing speed and stress output of microactuators, with respect to large scale actuators. Recently we developed a novel fabrication process to obtain robust large area, free standing, conductive ultra-thin films made of the conjugated polymer poly (3, 4-ethylenedioxythioph… Show more

“…PEDOT can be synthesized by electrochemical polymerization using an active supporting electrolyte or by oxidative chemical polymerization to obtain aqueous dispersions stabilized by a water-soluble poly(styrene sulfonate) [15][16][17]. In last years, PEDOT and its derivatives have been widely applied in the energy field, as for example to fabricate the cathode and anode in all-organic supercapacitors [18,19], electrochemical microactuators [20], and catalysts for polymer electrolyte fuel cells [21,22]. Furthermore, in a very recent study, solidstate organic electrochemical supercapacitors have been fabricated combining PEDOT 3 electrodes, a biohydrogel as electrolyte system, and polyaniline fibers as redox additive [23].…”

“…After their release in water from their temporary substrate, nanosheets can be manipulated as freestanding films, characterized by ultraconformability on any surface. Circuits were patterned on board of bilayer poly(lactic acid):PEDOT:PSS nanosheets and similar nanosheets have been tested as ultrathin actuators and sensors …”

“…VPP PEDOT shows only minor fractional changes upon bending of 0.12 AE 0.04, where as PEDOT:PSS showed an average fractional change of 0.3 AE 0.1. When conducting polymers undergo tension there are two mechanisms that generally alter resistance of the film: alignment of the polymer chains and potential volume change due to ion exchange [45][46][47][48]. Since these films are not in liquid, the potential for ion exchange due to volume difference during stretching is low, so the altered change in resistance is likely due to alignment of the polymer chains.…”
