水响应型执行器在各种应用中受到越来越多的关注。本文以商品化的PVA和SBS为原料，采用两步溶液浇铸法制备了基于双层复合膜的水响应型致动器。为了改善PVA层和SBS层之间的粘附性，首先对SBS进行了环氧化处理，以改善其极性。在环氧化SBS(E-SBS)/四氢呋喃溶液表面形成薄膜后，立即将PVA水溶液倒在薄膜上并干燥。结果表明，两层间的结合性能得到了改善，结合强度达到1005kPa.所得双层膜具有水响应型双向形状记忆效应，并在5次循环中表现出优异的循环性能。制备了基于双层复合膜的花状和爪状致动器，并对其驱动性能进行了测试，表明其在生物医学和传感器领域具有潜在的应用前景。
Water-responsive actuators have been of increasing interest in various applications. In this work, water-responsive actuators based on the bilayer composite film were prepared using commercialized PVA and SBS by a two-step solution casting method. In order to improve the adhesion between the PVA layer and SBS layer, SBS was firstly epoxidized to improve the polarity. Immediately after a thin film was formed on the surface of the epoxidized-SBS (E-SBS)/tetrahydrofuran solution, the PVA aqueous solution was poured onto the film and dried. It was found that the adhesive property between the two layers was improved and the adhesion strength reached 1005 kPa. The resultant bilayer film displayed the water-responsive two-way shape memory effect and exhibited excellent cyclic performance in five cycles. Flower-like and claw-like actuators based on the bilayer composite film were prepared and the actuation performance was demonstrated, suggesting their potential for applications in the fields of biomedicine and sensors.
