采用定向结晶技术制备了面内各向异性的P3 HT薄膜，并研究了不同取向晶粒间晶界的电荷输运特性。与纤维-纤维晶界相比，沿纤维的晶界沿着为电荷传输提供了小的屏障。该薄膜允许在P3 HT中的晶界类型和电荷转移行为之间绘制相关性
P3HT films that are highly anisotropic inplane are produced using a directional crystallization technique, and the charge-transport properties of grain boundaries between different orientations of crystallites are studied. Boundaries along the fiber provide a small barrier to charge transport when compared to fiber-to-fiber grain boundaries. The films allow a correlation to be drawn between the grain-boundary type and charge-tran sport behavior in P3HT
