Abstract

This paper introduces a carbonyl iron–PDMS (CI–PDMS) composite magnetic elastomer in which carbonyl iron (CI) particles are uniformly distributed in a PDMS matrix. The CI particles and the PDMS were mixed at different weight ratios and tested to determine the influence ofCI concentration. Themagnetic and mechanical properties of the magnetic elastomers were characterized, respectively, by vibrating-sample magnetometer and by tensile testing using a mechanical analyzer. The elastomerwas found to exhibit high magnetization and good mechanical flexibility. The morphology and deformation of the CI–PDMS membrane also were observed. A magnetically actuated microfluidic mixer (that is, a micromixer) integrated with CI–PDMS elastomer membranes was successfully designed and fabricated. The high efficiency and quality of the mixing makes possible the impressive potential applications of this unique CI–PDMS material in microfluidic systems.
