在这项研究中，我们成功地制造了一种新型的纳米纤维水凝胶致动器，该致动器基于溴酸盐/亚硫酸盐/亚铁氰化物反应，引起与外部pH振荡同步的弯曲和拉伸运动。新型纳米纤维凝胶致动器是由丙烯酸和疏水甲基丙烯酸丁酯作为溶解度控制位点共聚合成的静电纺丝纳米纤维组成的。通过改变静电纺丝流量，纳米纤维凝胶致动器在凝胶中引入了各向异性的内部结构。因此，产生了纳米纤维作动器的不对称运动。
In this study, we succeeded in manufacturing a novel nanofiber hydrogel actuator that caused a bending and stretching motion synchronized with external pH oscillation, based on a bromate/sulfite/ferrocyanide reaction. The novel nanofiber gel actuator was composed of electrospun nanofibers synthesized by copolymerizing acrylic acid and hydrophobic butyl methacrylate as a solubility control site. By changing the electrospinning flow rate, the nanofiber gel actuator introduced an anisotropic internal structure into the gel. Therefore, the unsymmetrical motion of the nanofiber actuator was generated.
