    Fatigue Properties of Organic Ferroelectric Nano-Film with Electroactive Interlayer

    • 摘要: 采用3种类型的电活性界面层材料,如高介电常数材料酞菁铜(CuPc)、电子导体原位合成的聚(乙撑二氧噻吩)-聚(苯乙烯磺酸)(PEDOT-PSSH)以及离子导体聚乙烯基磷酸(PVPA)和商业的PEDOT-PSSH (BaytronP),研究了界面层对铁电共聚物薄膜的疲劳特性的影响。研究结果表明,三种类型的电活性界面层材料,包括电子、离子导体和含偶极子的高介电常数材料都能为铁电薄膜提供补偿电荷从而提高器件的铁电疲劳性能。

       

      Abstract: A series of ferroelectric polarization reversal measurements were conducted on spin-coating ultrathin poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) copolymer films sandwiched with different electroactive materials between P(VDF-TrFE) and metal electrode. Three types of electroactive interlayers, including highly polarized material copper-phthalocyanine (CuPc), electron conductor poly(ethylene dioxythiophene)-poly(styrene sulfonate acid)(PEDOT-PSSH) and ion proton conductor poly(vinyl phosphonic) acid (PVPA) were employed. Results showed that the compensated charges from electroative interlayers, such as electrons, protons, as well as dipoles, would improve the fatigue behaviors of electronic devices.
