| Abstract Scope |
The development of active materials, able to respond to an external stimulus, are a demand in the current era of Internet of Things (IoT). The ones with magnetic properties are particularly interesting due to their capacity to be wirelessly activated. Those are usually obtained by dispersing micro- or nano-sized magnetic particles into a polymeric matrix. Due to its thermoplastic properties, polyurethanes (PUs), stands out as an appropriated option.
In this work, we aim to provide an insight on polyurethane based magnetic active material filled with different concentrations of CoFe2O4, in the range of 35-55 nm, and with different thickness. The process of synthesis was optimized and the morphological, mechanical and thermal characterization was performed. Finally, the actuator and magnetorheological behavior of the prepared composites were analyzed to improve their performance as microvalves in microfluidic devices. |
