摘要

磁流变弹性体（MRE）是一种用于传感器、吸收器和阻尼器的智能材料，备受关注。将弹性体和添加剂整合在一起的羰基铁颗粒经常出现。然而，羰基铁颗粒的制造过程既耗时又复杂，而且羰基涂层还会降低磁流变（MR）效应。为了解决这些难题，本研究采用了简便的制造工艺，同时 MRE 显示出适当的循环稳定性和良好的磁流变效果。压缩 30 次后，输出应力几乎达到饱和。绝对和相对磁共振效应分别达到 1.11 兆帕和 33.3%，临界值介于 16Fe 和 24Fe 复合材料之间。

A facile fabrication for the magnetorheological elastomer composed of Fe particles and silicone rubber matrix

Magnetorheological elastomers (MREs), smart materials for sensors, absorbers, and dampers, have attracted great attention. Carbonyl Fe particles integrating an elastomer and additives are often seen. Nonetheless, time-consuming and complicated fabrication processes are encountered, and the carbonyl coating also deteriorates the magnetorheological (MR) effect. This study, to solve these dilemmas, worked on a facile fabrication process, while MREs show proper cyclic stability and good MR effect. The output stress is almost saturated after 30 times of compression. The absolute and relative MR effects of 1.11 MPa and 33.3 % were achieved, and the threshold value is located between 16Fe and 24Fe composites.
