Composed exclusively of organic components, polyaniline (PANi), graphene, and double-walled nanotubes (DWNTs) are alternately deposited from aqueous solutions using a layer-by-layer assembly. The 40 quadlayer thin film (470 nm thick) exhibits electrical conductivity of 1.08 × 10(5) S m(-1) and a Seebeck coefficient of 130 μV K(-1) , producing a thermoelectric power factor of 1825 μW m(-1) K(-2) .
聚苯胺（PANI）、石墨烯和双壁纳米管（DWNTs）完全由有机成分组成，通过逐层组装从水溶液中交替沉积。40 个四层薄膜（厚 470nm）的电导率为 1.08×10^5 S m^(-1)，塞贝克系数为 130 μV K^(-1)，产生的热电功率因子为 1825 μW m^(-1) K^(-2)。
