We report a facile strategy to synthesized the PPy-DBSA-Y₂O₃ composites with increasing amount of Y₂O₃ (2%, 4% and 8%) by in situ polymerization method. The samples were characterized by XRD, FTIR, SEM and dielectric spectroscopy. Structural and morphological analysis reveals the conformation of composite formation, increase in crystallinity and particle size also increased by doping Y₂O₃ into PPy-DBSA matrix. The frequency dependent AC conductivity (σ_ac), dielectric constant (ε′) and loss factor (ε″) were measured in the frequency range from 20 Hz to 1 MHz. All measured quantities; σ_ac, ε′ and ε″ are enhanced with increase in Y₂O₃ content in the composites at all frequencies. Dielectric constant value for all samples is very high at low frequency however decreases with increase in frequency. Synthesis of PPy-DBSA-Y₂O₃ composite materials with a large dielectric constant is very important for the improvement of electronic devices applications.

十二烷基苯磺酸掺杂的聚吡咯/纳米Y 2 O 3复合材料的结构，电和介电性能

我们报道了一种简便的策略，通过原位聚合方法合成了具有增加的Y ₂ O ₃含量（2％，4％和8％）的PPy-DBSA-Y ₂ O ₃复合材料。通过XRD，FTIR，SEM和介电谱对样品进行表征。结构和形态分析表明，通过将Y ₂ O ₃掺杂到PPy-DBSA基质中，可以形成复合物的构象，结晶度的增加和粒径的增加。频率相关AC电导率（σ _AC），介电常数（ε'）和损耗因子（ε“）的频率范围内进行测量，从20Hz至1MHz。所有测量数量；σ_交流，ε'和ε“增强并具有沿Y增加复合材料在所有频率下的₂ O ₃含量。所有样品的介电常数值在低频下都很高，但是随频率增加而降低。具有大介电常数的PPy-DBSA-Y ₂ O ₃复合材料的合成对于改善电子设备的应用非常重要。
