Ionic polymer composite membranes based on sulfonated poly(arylene ether sulfone) (SPAES) and copper(II) phthalocyanine tetrasulfonic acid (CuPCSA) are assembled into bending ionic polymer actuators. CuPCSA is an organic filler with very high sulfonation degree (IEC = 4.5 mmol H⁺/g) that can be homogeneously dispersed on the molecular scale into the SPAES membrane, probably due to its good dispersibility in SPAES-containing solutions. SPAES/CuPCSA actuators exhibit larger ion conductivity (102 mS cm^–1), tensile modulus (208 MPa), strength (101 MPa), and strain (1.21%), exceptionally faster response to electrical stimuli, and larger mechanical power density (3028 W m^–3) than ever reported for ion-conducting polymer actuators. This outstanding actuation performance of SPAES/CuPCSA composite membrane actuators makes them attractive for next-generation transducers with high power density, which are currently developed, e.g., for underwater propulsion and endoscopic surgery.

用于高功率密度和快速响应时间的离子聚合物致动器的磺化酞菁铜/磺化聚砜复合膜

将基于磺化聚亚芳基醚砜（SPAES）和铜（II）酞菁四磺酸（CuPCSA）的离子聚合物复合膜组装成弯曲的离子聚合物致动器。CuPCSA是一种具有很高磺化度（IEC = 4.5 mmol H ⁺ / g）的有机填料，可以在分子尺度上均匀分散在SPAES膜中，这可能是由于其在含SPAES的溶液中具有良好的分散性。SPAES / CuPCSA执行器具有更大的离子传导率（102 mS cm ^–1），拉伸模量（208 MPa），强度（101 MPa）和应变（1.21％），对电刺激的响应速度更快，以及更大的机械功率密度（3028）宽m ^–3），这比离子导电聚合物致动器的报道要多。SPAES / CuPCSA复合膜致动器的出色致动性能使它们吸引了具有高功率密度的下一代换能器，这些换能器目前正在开发中，例如用于水下推进和内窥镜手术。
