ABSTRACT

Impedance spectroscopy-based electrical measurements were conducted on different molecular weight (MW) Poly(1,6-heptadiyne)s (PHDs) embedded PHD/NiFe2O4 nanocomposites. Nanocomposites conductivity result demonstrated the conductivities of around 3.5 × 10 6 16 × 10 6 S C m 1 (nanocomposite Root mean square (RMS) current is 12–15 times greater than DC current of PHDs at 27° C). Additionally, dielectric loss and capacitance characteristics suggested the nanocomposite (4500 MW PHD) device quality factor is 35.7 at 1 kHz, which is ~13.89 times superior than that of NiFe2O4 alone sample, also ‘Q’ value for highest MW PHD nanocomposite is 50% enhanced than NiFe2O4. Moreover, the capacitance result suggested the 12400 MW PHD nanocomposite nearly frequency-independent capacitance (15–20pF) over a frequency range of 500 Hz–500 kHz.

摘要

在不同分子量(MW)的PHD / NiFe 2 O 4纳米复合材料中,对不同分子量(MW)的聚(1,6-庚二炔)(PHDs)进行了基于阻抗谱的电测量。纳米复合材料的电导率结果表明 3.5 × 10 - 6 - 16 × 10 - 6 小号 C - 1个 (纳米复合均方根(RMS)电流是27°C时PHD的DC电流的12–15倍)。此外,介电损耗和电容特性表明,纳米复合材料(4500 MW PHD)的器件品质因数在1 kHz时为35.7,比单独的NiFe 2 O 4样品高约13.89倍,也是最高MW PHD纳米复合材料的'Q'值比NiFe 2 O 4增强50%。此外,电容结果表明12400 MW PHD纳米复合材料在500 Hz至500 kHz的频率范围内具有几乎与频率无关的电容(15-20pF)。
