| 제목 | Magnetoelectric electrospun-P(VDF-TrFE) nanofibers embedded with cellulose nanocrystal/CoFe₂O₄ nanocomplex for magnetic sensors |
| 초록 | Sinceseveral decades, a great deal of research regarding cellulose nanocrystal (CNC)has been performed due to its unique characteristics such as high aspect ratio,high zeta potential, abundant hydroxyl groups on the surface, to name a few.Among these features, the hydroxyl groups could be a key not only solves an electricalleakage in magnetoelectric (ME) composites, but also enhances the stimulusoriginated from magnetostictive phase, resulting in high ME coupling. Inthis study, CNC/CoFe2O4 nanocomplex synthesized by aone-step hydrothermal method was designed. CoFe2O4precursors were mixed in ultra-sonicated CNC dispersion followed byhydrothermal synthesis. The prepared nanocomplex, subsequently, was moved toP(VDF-TrFE) solution. The solution was then spun onto a rotating drum viaelectrospinning process. Ferroelectric, ferromagnetic, and ME properties were finallyinvestigated along with various characterizing including SEM, XRD, FT-IR, XPS,and thermal analysis. |
