Recently, the thermoelectric (TE) functions of Poly(3,4-ethylene-dioxythiophene):Poly(styrenesulphonate) (PEDOT:PSS) polymer have been extensively progressed, owing to its processability, flexibility, and its low intrinsic thermal conductivity. In this regards, nickel oxide (NiO) nano-particles have been mixed with PEDOT:PSS to design a new thermoelectric (PEDOT:PSS/NiO) system. The anisotropic (parallel // and vertical ⊥) TE functions as a function of the NiO content (10–40 wt%) have been investigated in the temperature range 300–390 K. The anisotropic conductivity (σ) of the systems is reduced while their anisotropic Seebeck coefficients (S) have increased with the increase in the NiO content. The anisotropic conductivity of the systems is reduced while their anisotropic Seebeck coefficients have increased firstly and then decrease with the growth of temperature. The optimal PF_//~24.61 ± 0.3 μW/mK² and PF_⊥~ 3.40 ± 0.03 μW/mK² are achieved at 340 K for 30 wt% with S_// ~39.07 ± 1.7 μV/K and S_⊥~27.34 ± 2 μV/K owing to the spin Seebeck coefficient, the reduction in the carrier concentration and the energy filtering effects. Interestingly, the impact of H₂SO₄ acid post-treatment on the PEDOT:PSS/NiO (30 wt%) has been done to obtain the highest PF values (PF_//~ 54.59 ± 1 μW/mK², PF_⊥~ 5.64 ± 2 μW/mK²) owing to the growth in the anisotropic σ as a result of the removal of PSS polymers. Finally, the achieved PEDOT:PSS/NiO system offers a promising TE functions for potential applications in temperature sensors, wearable electronics and harvest technology.

最近，聚（3,4-乙烯-二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）聚合物的热电（TE）功能由于其可加工性、柔韧性和低固有热导率而得到了广泛的发展。在这方面，已将氧化镍 (NiO) 纳米颗粒与 PEDOT:PSS 混合以设计一种新的热电 (PEDOT:PSS/NiO) 系统。已在 300-390 K 的温度范围内研究了各向异性（平行 // 和垂直 ⊥）TE 函数作为 NiO 含量（10-40 wt%）的函数。系统的各向异性电导率（σ）降低，而它们的各向异性塞贝克系数 ( S) 随着 NiO 含量的增加而增加。系统各向异性电导率降低，各向异性塞贝克系数随温度升高先增大后减小。最佳PF _// ~24.61 ± 0.3 μW/mK ²和PF _⊥ ~ 3.40 ± 0.03 μW/mK ²在 340 K 时达到 30 wt% S _// ~39.07 ± 1.7 μV/K 和S _⊥ ~27.34 ± 2 μV/K 由于自旋塞贝克系数、载流子浓度的降低和能量过滤效应。有趣的是，H ₂ SO _4的影响对 PEDOT:PSS/NiO (30 wt%) 进行酸后处理以获得最高的PF值 ( PF _// ~ 54.59 ± 1 μW/mK ² , PF _⊥ ~ 5.64 ± 2 μW/mK ² )由于 PSS 聚合物的去除，各向异性σ的增长。最后，所实现的 PEDOT:PSS/NiO 系统为温度传感器、可穿戴电子设备和收获技术的潜在应用提供了有前途的 TE 功能。
