论文摘要
我们提出了一种通过在涂层时在溶液中光学兴奋的p型聚合物来操纵卷到卷式涂层涂层聚（3-己基噻吩）（P3HT）的最终形态的方法。我们的结果为整个知识链提供了全面的了解，从展示如何运用我们的方法到对涂层时令人兴奋的P3HT引起的形态和物理特性变化的基本了解。通过将密度功能理论和分子动力学模拟的结果与多种X射线实验，吸收光谱和THZ光谱相结合，我们证明了薄膜的形态与物理特性之间的关系。具体而言，在沉积过程中用光激发的P3HT膜中，我们观察到结晶度和质地的变化，面向式方向更多，并增加了平面外电荷迁移率。
We present a method to manipulate the final morphology of roll-to-roll slot-die coated poly(3-hexylthiophene) (P3HT) by optically exciting the p-type polymer in solution while coating. Our results provide a comprehensive picture of the entire knowledge chain, from demonstrating how to apply our method to a fundamental understanding of the changes in morphology and physical properties induced by exciting P3HT while coating. By combining results from density functional theory and molecular dynamics simulations with a variety of X-ray experiments, absorption spectroscopy, and THz spectroscopy, we demonstrate the relationship between morphology and physical properties of the thin film. Specifically, in P3HT films excited with light during deposition, we observe changes in crystallinity and texture with more face-on orientation and increased out-of-plane charge mobility.
