在本研究中，研究了聚(3,4-乙烯二氧基噻吩):聚(苯乙烯-4-磺酸)(PEDOT:PSS)/磷酸硼(BPO4)形成的复合材料的热电性能。首先，使用硼酸和磷酸作为前体在 1000 摄氏度下合成 BPO(4)。随后在室温下通过氧化化学聚合反应合成了PEDOT:PSS。通过超声均化制备不同质量比的复合材料。使用紫外-可见光 (UV-vis.)、衰减全反射附件附加傅里叶变换红外 (FTIR-ATR) 光谱、X 射线衍射 (XRD) 和扫描电子显微镜/能量色散 X 射线分析仪 (SEM-EDX) 对复合材料进行表征。使用电导率和塞贝克系数测量获得样品的功率因数。添加BPO4后，原始PEDOT:PSS的塞贝克系数由正值变为负值，这是n型材料的特点。对于含有25%重量比的BPO4的复合材料，PEDOT:PSS的功率因数从0.03μWm(-1)K-2增加到252μWm(-1)K-2。这表明BPO4可以作为制备型TE材料的良好添加剂。形象的
In the present study, thermoelectric properties of composites formed by poly (3,4-ethylenedioxy thiophene):poly (styrene-4-sulfonate) (PEDOT:PSS)/boron phosphate (BPO4) were studied. First, BPO(4)was synthesized at 1000 degrees C using boric acid and phosphoric acid as precursors. Later, PEDOT:PSS was synthesized by oxidative chemical polymerization reaction at room temperature. Their composites were prepared in different mass ratios by ultrasonic homogenization. The composites were characterized using ultraviolet-visible (UV-vis.), attenuated total reflection accessory attached Fourier transform infrared (FTIR-ATR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy/energy dispersive X-ray analyzer (SEM-EDX). The power factor of the sample was obtained using the electrical conductivity and Seebeck coefficient measurements. The positive sign of Seebeck coefficient of the pristine PEDOT:PSS turned to the negative, which is the characteristic ofn-typematerial, by addition of BPO4. The power factor of PEDOT:PSS was increased from 0.03 mu Wm(-1) K-2 to 252 mu Wm(-1) K-2 for the composite containing 25% BPO4 by weight. This indicates that BPO4 can be a good additive to preparen-typeTE material. Graphic
