The different impacts of graphene (GNS) and multi-walled carbon nanotube (MWCNT) on the polypyrrole (PPy)-based composites systems have been investigated. PPy/GNS and PPy/MWCNT binary composites were firstly obtained by in situ polymerization. Then poly(3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) was employed to prepare PEDOT: PSS-PPy/GNS (PGNS) and PEDOT: PSS-PPy/MWCNT (PMWCNT) ternary nanocomposite films. PGNS films exhibit uniform layered structure and possess better crystallinity than PMWCNT composites films. Structural analyses reveal that PPy/GNS interact stronger with PEDOT chains, and PEDOT molecular has greater effect on the π-π conjugated structure of PPy/GNS than that of PPy/MWCNT. In particular, when the mass ratio of PPy/GNS to PEDOT: PSS was 70%, PGNS composites show excellent thermoelectric performance with the maximum power factor at room temperature of 82.22μW/mK², which is among the highest value of PPy/GNS-based composites, and the optimal power factor of 55.28μW/mK² goes to PMWCNT films when the mass ratio of PPy/MWCNT to PEDOT: PSS was 5%.

研究了石墨烯（GNS）和多壁碳纳米管（MWCNT）对基于聚吡咯（PPy）的复合材料系统的不同影响。PPy / GNS和PPy / MWCNT二元复合材料首先通过原位获得聚合。然后，使用聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）制备PEDOT：PSS-PPy / GNS（PGNS）和PEDOT：PSS-PPy / MWCNT（PMWCNT）三元纳米复合薄膜。PGNS薄膜具有均匀的层状结构，并且比PMWCNT复合薄膜具有更好的结晶度。结构分析表明，PPy / GNS与PEDOT链的相互作用更强，与PPy / MWCNT相比，PEDOT分子对PPy / GNS的π-π共轭结构的影响更大。尤其是当PPy / GNS与PEDOT：PSS的质量比为70％时，PGNS复合材料表现出优异的热电性能，室温下的最大功率因数为82.22μW/ mK ²，这是PPy / GNS的最高值基复合材料，最佳功率因数55.28μW/ mK ² 当PPy / MWCNT与PEDOT：PSS的质量比为5％时，PMWCNT膜会变质。
