Abstract Generally, magnetostriction elastomer were based on magnetic field-induced strains of elastomer matrix, resulting from the rotation of magnetic particle in elastomer matrix. However, such magnetostriction was relatively small and large hysteresis. Here, a new class magnetic rubber foam with cellular structure was developed and synthesized by the one-step solution foam processing. The magnetic rubber foam did not only show larger magnetostriction value of ca.11.0% comparing to previous magnetostriction elastomer, but also was few remanent magnetostriction and rapid response (ca. 1.0s). Furthermore, a new mechanism of magnetostriction was proposed for explaining the high performance magnetostriction. These provide a universal route for the rational design of magnetostriction materials with high performance for various applications.

一步溶液泡沫法制备具有蜂窝结构的磁性橡胶泡沫用于超磁致伸缩

摘要 通常，磁致伸缩弹性体是基于弹性体基体的磁场诱导应变，由弹性体基体中的磁性粒子旋转产生。然而，这种磁致伸缩相对较小且滞后较大。在这里，通过一步溶液泡沫加工开发并合成了一种具有多孔结构的新型磁性橡胶泡沫。与以前的磁致伸缩弹性体相比，磁性橡胶泡沫不仅显示出更大的磁致伸缩值，约为 11.0%，而且剩余磁致伸缩很少，响应速度快（约 1.0 秒）。此外，提出了一种新的磁致伸缩机制来解释高性能磁致伸缩。这些为合理设计用于各种应用的高性能磁致伸缩材料提供了通用途径。
