제목 Investigation of bimorph actuators based on conductive polymer films
초록 Conducting polymer actuator has been intensively studied due to large displacement of low voltage and their potential applications. But in general the bi-layer actuators have a significant problem as delamination process between insulating layer and conducting polymer layer1. In suit polymerization using molecular self-assembly in aqueous solution was utilized to improve interfacial adhesion of them. Fig.1 shows the procedure for fabrication of PPy/sulfonated PVDF-g-PS actuator. First, polyvinylidene fluoride-g-polystyrene (PVDF-g-PS) as the non-conducting polymer was synthesied by grafting with styrene monomers using γ-rays or UV2. And the surface-sulfonated PVDF-g-PS was processed with chlorosulfuric acid. Second, the bimorph-type actuators were formed by chemical oxidation of pyrrole or 3,4-ethylenedioxythiophene monomer on surface-sulfonated PVDF-g-PS. The degree of surface-sulfonation was determined from the change of weight and characterized by ATR-IR and FE-SEM. The behaviors and properties of the bimorph actuators were characterized by using laser displacement meter and cyclic voltammetry.
