| 제목 | Magnetoelectric responses in 3-2 type polymer composite films using 2D magnetostrictive fillers |
| 초록 | Polymer-based magnetoelectric (ME) composites have been studied due to their potential applications such as energy harvesters and sensors. Among the polymer ME composites, particulate composites have developed using several shapes of magnetostrictive fillers with 0D nanoparticles and 1D nanorods/nanotubes because the shape of fillers is a critical determinant to decide β-phase in piezoelectric polymers, strain transfer to piezoelectric phase, and leakage current during poling as well. In this study, we prepared 3-2 type polymer ME composites using 2D magntostrictive fillers of CoFe2O4-intercalated GO (CFO-i-GO) and piezoelectric matrix of PVDF. Then, magnetoelectric responses in the PVDF/CFO-i-GO composite films were investigated with regard to lateral size effect of CFO-i-GO on piezoelectric properties. As a result, maximum value of ME coefficient was obtained with magnitude of 3.0 mV/cm·Oe at magnetic bias field of 1000 Oe under frequency of 1 kHz from the ME composite films. |
