论文摘要
可切换的粘合剂有可能改善零件的制造和回收利用，并为软机器人提供新的运动模式。在这里，我们展示了两相复合物对非磁性物体的磁性连接粘附。该复合材料的连续相是硅酮弹性体，分散相是一种磁性流体。该复合材料简单地准备，并塑造不同形状。当应用磁场时，磁性流体会产生屈服应力，从而极大地增强了复合材料的粘附特性。在存在250吨场的情况下，我们证明了非磁物体的拉力增加力增加了9倍。
Switchable adhesives have the potential to improve the manufacturing and recycling of parts and to enable new modes of motility for soft robots. Here, we demonstrate magnetically-switchable adhesion of a two-phase composite to non-magnetic objects. The composite's continuous phase is a silicone elastomer, and the dispersed phase is a magneto-rheological fluid. The composite is simple to prepare, and to mould to different shapes. When a magnetic field is applied, the magneto-rheological fluid develops a yield stress, which dramatically enhances the composite's adhesive properties. We demonstrate up to a nine-fold increase of the pull-off force of non-magnetic objects in the presence of a 250 mT field.
