摘要: 柔性电子元件的发展日新月异,其中有机薄膜因具有延展性、柔韧性、易制备等优点,使其在智能可穿戴柔性器件领域有着巨大的应用潜力.采用溶胶-凝胶法,利用有机聚合物P(VDF-TrFE)共聚物和有机磁性材料二茂铁间苯甲酰腙(FOM)在柔性聚酰亚胺(PI)衬底上成功制备了0-3型纳米复合薄膜.结构表征表明,FOM纳米颗粒均匀地分布在P(VDF-TrFE)基质中.纳米复合材料的晶体和微观结构取决于P(VDF-TrFE)和FOM的物质的量比,铁电和磁电响应受到FOM纳米粒子浓度的强烈影响.纳米复合薄膜的磁电耦合系数最高为15.1 mV/(cm·Oe)

Abstract: The development of flexible electronic components is changing with each passing day. Due to the advantages of ductility, flexibility, and easy preparation, organic thin films have considerable application prospects in the field of smart wearable flexible devices. 0-3 type nanocomposite film composed of organic polymer P(VDF-TrFE)copolymer and organic magnetic material ferrocene-m-benzoylhydrazone(FOM)was prepared on flexible polyimide(PI)substrate by sol-gel method. Structural characterization shows that the FOM nanoparticles are uniformly distributed in the P(VDF-TrFE)matrix. The crystalization and microstructure of the nanocomposites relays on the molar ratio of P(VDF-TrFE)and FOM, and the ferroelectric and magnetoelectric responses are strongly affected by the concentration of FOM nanoparticles. A remarkable magnetoelectric coupling effect of about 15.1 mV/(cm·Oe)is obtained from the nanocomposite film.

Key words: 0-3 type structure, magnetoelectric coupling effect, organic composite film
