我们报道了研究聚合物薄膜在平面内和穿过平面方向上的热电特性的一般方法。基准PEDOT/PSS薄膜具有高度的各向异性载流子输运性能和导热性。PEDOT/PSS薄膜的层状结构可以解释PEDOT/PSS薄膜的各向异性载流子输运特性，其中PEDOT纳米晶体可以被绝缘的PSS在通平面方向上隔离。各向异性导热性主要归因于PSS的晶格贡献，因为聚合物链沿着衬底取向。
We reported general methods for studying the thermoelectric properties of a polymer film in both the in-plane and through-plane directions. The bench-mark PEDOT/PSS films have highly anisotropic carrier transport properties and thermal conductivity. The anisotropic carrier transport properties can be explained by the lamellar structure of the PEDOT/PSS films where the PEDOT nanocrystals could be isolated by the insulating PSS in the through-plane direction. The anisotropic thermal conductivity was mainly attributed to the lattice contribution from PSS because the polymer chain is oriented along the substrate.
