The optimal thermoelectric property of poly(Ni-ett) synthesized at 0.6 V is remarkably greater than that of the polymers synthesized at 1 and 1.6 V, exhibiting a maximum power factor of up to 131.6 μW/mK^2 at 360 K. Furthermore, the structure-property correlation of poly(Ni-ett) is also extensively investigated. X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS) analyses revealed that the larger size of crystalline domains and the higher oxidation state of poly(Ni-ett) synthesized at 0.6 V possibly results in the higher bulk mobility and carrier concentration in the polymer chains, respectively, accounting for the enhanced power factor. 关 键 词：恒电位沉积法 合成聚合物 n型热电材料 镍(Ⅱ) 性能优化 X射线光电子能谱 配位聚合物 高功率因数
