相較於無機材料，有機半導體的可溶性使得製程上可以大幅的簡化，能透過溶液塗佈法取得薄膜，如 旋轉塗佈、噴墨塗佈等。然而有機共軛高分子的溶解度並不好，由於其線性長鏈的結構，使高分子 高分子的作用力比高分子 溶劑分子的作用力強，溶劑不易溶脹高分子鏈，在溶液狀態裡，高分子鏈長呈現糾纏且聚集的構型。
目前的文獻中，透過改變溶劑，並選擇該高分子的good solvent，可以溶脹高分子鏈使其延展開，然而如果good solvent是高沸點溶劑，在塗佈的過程會發生去濕現象，因此無法在溶液與薄膜狀態達到平衡。Elsa Reichmanis教授使用外部刺激的方式，將高分子溶液進行超音波震盪，卻未看見高分子鏈展開的光譜現象。
因此我們將微波爐的原理帶到研究中，微波中受到變動的電場旋轉極性溶劑分子，能夠解開糾纏聚集的高分子鏈。透過建立實時(in-situ) 系統與光譜結合，使用了UV 吸收光譜、螢光光譜以及小角度X-ray 散射，分析高分子構型的變化。由於微波輻射會提高溫度是無法避免的，因此水浴加熱做為對照組，並排除了溫度效應。接著進行原子力顯微鏡及廣角X-ray散射的量測，觀察高分子薄膜型態及結晶，不僅結晶度增加，更多精細的纖維結構亦形成。這些結構的優點反映在電性量測上，僅需要數秒的輻射，就可以優化高分子的載子遷移率數倍，若與噴墨塗佈法結合，達到連續化的製程，則將大幅提升有機共軛高分子的潛力。

Compared to inorganic materials, the solubility of organic semiconductors enables a greatly simplified manufacturing process, where thin films can be obtained through solution deposition methods such as spin-coating and inkjet printing. However, the poor solubility of organic conjugated polymers, due to their linear chain structure, results in stronger polymer-polymer interactions than polymer-solvent interactions, making it difficult for solvents to swell and disperse the polymer chains. As a result, in solution, the polymer chains tend to become entangled and aggregate.
In previous studies, the use of good solvents for the polymer has been shown to swell and extend the polymer chains. However, if the good solvent is a high-boiling point solvent, the dewetting phenomenon occurs during the coating process, making it difficult to achieve equilibrium between the solution and the film state. Professor Elsa Reichmanis used external stimuli to vibrate the polymer solution with ultrasound, but no spectral phenomenon indicating chain extension was observed.
This study investigates the use of microwave radiation as a novel method for manipulating polymer solutions and optimizing the performance of polymer thin films. By analyzing changes in polymer configuration and morphology using spectroscopic and scattering techniques, we found that microwave radiation is capable of disrupting clusters, resulting in increased solubility and improved crystallinity. The resulting fine fibrous structures in the polymer film leads to an increase in carrier mobility, enhancing the potential of organic conjugated polymers. Compared to conventional heating, the microwave method is faster and more effective, making it a promising commercial application. Real-time (in-situ) systems combined with spectroscopy provide a deeper understanding of the mechanism of microwave radiation, and can further optimize the conditions for using microwaves.
