導電高分子具備導電性和可撓性，其碳基主鏈特性使其在現代輕量化、小型化和低成本元件的發展趨勢中，成為非常適合應用於消費型或醫療型電子材料的選擇。然而，由於導電高分子的主鏈具可撓性且易發生扭曲，導致電子傳輸效率低下，這成為其發展的限制因素。先前研究表明，當高分子的微觀排列缺乏單一指向性時，會導致較低的載子遷移率，因此提高導電高分子材料的指向性成為首要目標。
在本實驗室鄭亘甫學長的碩士論文中，已成功搭建了自動化雷射微影系統。本研究將進一步改良其雷射光路，不僅製造出高解析度和高品質的電極，還將控制液相製程中的複雜分子間作用力，以製備高有序性的導電高分子薄膜，從而增強其載子傳導行為。本研究以高有序性的導電高分子薄膜與低表面能電極的結合，有望大幅提升載子傳輸效率。

Conductive polymers possess both conductivity and flexibility. The carbon-based backbone of these materials makes them particularly suitable for applications in consumer and medical electronic devices, especially in the context of modern trends toward lightweight, compact, and low-cost components. However, the flexibility of the polymer backbone also makes it prone to distortion, leading to low electron transport efficiency, which is a significant limitation for their development. Previous studies have shown that when the microstructure of the polymer lacks a single orientation, it results in lower carrier mobility. Therefore, improving the orientation of conductive polymer materials has become a primary goal.
In the master's thesis of Senior Keng-Fuu Cheng in our laboratory, an automated laser lithography system was successfully established. This research will further improve the laser optical path, not only to fabricate high-resolution and high-quality electrodes but also to control the complex intermolecular interactions during the solution processing. This will allow the fabrication of highly ordered conductive polymer films, thereby enhancing their carrier transport behavior. The combination of highly ordered conductive polymer films with low surface energy electrodes is expected to significantly improve carrier transport efficiency.
