Abstract

The invention discloses a ferromagnet composite polymer nanofilm. CFO serves as a core and is coated with insulated ferroelectric BT nanoparticles and a polydopamine (PDA) organic shell layer, the CFO@BT@PDA nanoparticles of a core-shell structure serve as an inorganic doping phase in a P(VDF-TrFE) polymer-based composite material, the inevitable agglomeration phenomenon of low-resistivity magnetic nanoparticles can be relieved, due to the high piezoelectric constant and dielectric constant of the insulated ferroelectric particles, the electrical performance of the film can be improved to a great extent, and the magnetoelectric effect is further improved.

Description

technical field

[0001] The invention belongs to the technical field of magnetoelectric material preparation, and in particular relates to a ferromagnetic composite polymer nano film and a preparation method of the nano film. Background technique

[0002] With the advancement of science and technology, the requirements for miniaturization and diversification of devices are getting higher and higher, which requires the development of new materials with two or more functions at the same time, so as to develop new devices that can realize multiple functions at the same time , multiferroic materials are one of the typical representatives. The concept of multiferroic materials was first clearly proposed by Schmid in Switzerland in 1994. This type of material contains two or more basic properties of iron, including ferroelectricity (antiferroelectricity), ferromagnetism (antiferromagnetism, ferrimagnetism) and ferroelasticity. All-in-one multifunctional materials have aroused gre...
