本论文采用直接真空过滤技术，通过一种简单的方法制备了纳米二氧化硅(poly(3，4-ethylenedioxythiophene)：poly(4-styrenesulfonate))/纳米二氧化硅(SiO_2-NPs)复合薄膜。系统研究了纳米SiO_2含量对PEDOT：PSS热电性能的影响。不加SiO_2-NPs的PEDOT：PSS纳米薄膜的最大电导率为1487 S cm−1，塞贝克系数为17.4 µV/K。当引入SiO_2-NPs时，当SiO_2-NPs的质量分数为20 时，PEDOT：PSS/SiO_2-NPs纳米复合薄膜的塞贝克系数达到峰值，达到24.2 µV/K，相应的电导率为1132 S/cm。尽管在电导率方面有所折衷，但由于改进的塞贝克系数的贡献，获得了高达66.29 微瓦/米k2的优化功率因数。SiO_2-NPs的存在可能会引起载流子散射和过滤效应，从而导致Seebeck系数的增大。
Herein, poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS)/silicon dioxide nanoparticles (SiO2-NPs) composite films were prepared via a simple method by direct vacuum filtration technique. The effect of SiO2-NPs contents on the thermoelectric performance of PEDOT:PSS was investigated systematically. PEDOT:PSS nanofilm without SiO2-NPs exhibited a maximum electrical conductivity of 1487 S cm−1 and a Seebeck coefficient of 17.4 µV/K. When the SiO2-NPs were introduced, the Seebeck coefficient of PEDOT:PSS/SiO2-NPs nanocomposite films increased to a peak value of 24.2 µV/K at 20 wt% SiO2-NPs, and the corresponding electrical conductivity was 1132 S/cm. Although a compromise in electrical conductivity, a large optimized power factor up to be 66.29 µW/m K2 was achieved due to the contribution of improved Seebeck coefficient. The presence of SiO2-NPs in the composite films with small-size structure and abundant grain boundaries may cause the carrier scattering and filtering effect, which accounts for the enhanced Seebeck coefficient.
