Abstract

In this paper, we develop multifunctional, physically soft, mechanically compliant, and magnetically responsive PDMS films, with embedded Fe₃O₄ nanoparticles, that show robust magnetic properties over a significant range of mechanical deformation. First, we establish that the magnetic properties, namely the saturation magnetization (M _s), remanent magnetization (M _r), and intrinsic coercivity (H _ci) of these PDMS films in highly deformed configurations, i.e. in folded, twisted (with different twist angles), and bent (flexed) configurations, show very little degradation compared to those obtained in undeformed configurations. Next, the films were subjected to repetitive cycles of zero-to-max deformation (R = 0) and the saturation magnetization of the films was shown to not exhibit any significant degree of progressive degradation as a function of cyclic deformation history. These findings confirm the excellent robustness and cyclic durability of magnetic properties shown by these magnetic and compliant PDMS films and point to their suitability for wearable electronics applications.

基于 PDMS-磁性纳米粒子的柔性可扭曲独立软磁薄膜，具有强大的磁性能

在本文中，我们开发了多功能、物理柔软、机械顺应性和磁响应的 PDMS 薄膜，其中嵌入了 Fe3O4 纳米粒子，在相当大的机械变形范围内显示出强大的磁性能。首先，我们确定了这些 PDMS 薄膜的磁特性，即饱和磁化 (Ms)、剩磁磁化 (Mr) 和本征矫顽力 (Hci)，在高度变形配置下，即在折叠、扭曲（具有不同的扭曲角度）和弯曲（弯曲）配置下，与未变形配置下获得的磁特性相比，几乎没有退化。接下来，对薄膜进行从零到最大的重复循环变形（R = 0），结果表明，薄膜的饱和磁化率不会随着循环变形历史的变化而出现任何明显的逐渐衰减。这些研究结果证实了这些具有磁性和顺应性的 PDMS 薄膜所表现出的卓越的稳健性和磁特性的循环耐久性，并指出它们适用于可穿戴电子产品应用。

期刊介绍： Flexible and Printed Electronics is a multidisciplinary journal publishing cutting edge research articles on electronics that can be either flexible, plastic, stretchable, conformable or printed. Research related to electronic materials, manufacturing techniques, components or systems which meets any one (or more) of the above criteria is suitable for publication in the journal. Subjects included in the journal range from flexible materials and printing techniques, design or modelling of electrical systems and components, advanced fabrication methods and bioelectronics, to the properties of devices and end user applications.
