Abstract

A novel magnetochromic elastomer with a strong and rapid magnetochromic effect has been developed. In the system, citric acid surface-functionalized magnetic nanoparticles (MNPs) are dissolved in poly(ethylene glycol) (PEG-200) and ultrasonicated into an emulsion with polydimethylsiloxane (PDMS) by speedmixing. The MNPs are shown to change from random to field-aligned under an external magnetic field and thus enables an on/off function. The developed elastomer shows a great potential for a wide range of applications, such as sensors and anticounterfeiting labels.
