Functional Polymer Composites Using Multiferroic Ceramic Nanofillers

Multiferroic materials exhibited more than one ferroic properties of piezoelectric, magnetostrictive, and magnetoelectric. Among the multiferroic materials, magnetoelectric (ME) materials coexisting ferroelectric and ferromagnetic properties has attracted great attention due to its unique applications such as energy harvesters, highly-sensitive magnetic sensors, actuators, memory devices. With the increase in demand of flexible and multifunctional electronic devices, polymer-based ME composites consisting of ferroelectric polymer matrix and ferromagnetic ceramic nanofillers have been developed by optimization of materials, structure, and process. In this review, we described research history and feasible applications for the polymer-based ME composites. We believe that the polymer-based ME composites can be a potential candidate for self-powered energy and sensing devices relevant to the fourth industrial revolution in the near future.
