聚醯亞胺（PI）是一種具有優異性能的高分子材料，其溫度穩定性佳、耐溶劑性且擁有高機械強度。因此聚醯亞胺在航太工業及醫療、電子設備等領域應用廣泛。其中具有高透明性的透明聚醯亞胺膜在光學及軟性電子產品應用上亦具有優勢。本論文主要以刮刀塗佈製程技術製備聚醯亞胺薄膜，主要以製程的角度來探討製程參數對薄膜特性及外觀所造成之影響。
本論文的工作可以分成兩部分。在第一部分中，使用了聚醯胺酸的塗料，以可調間隙之手持刮刀機進行塗佈，並利用不同的製程參數分別製備出不同的聚醯胺酸薄膜，之後再高溫烘烤脫水環化為聚醯亞胺膜，並對其進行一系列光學特性、機械特性、熱特性及外觀之分析與比較。
第二部分為使用塗佈均勻性較佳之狹縫式塗佈法進行連續性的捲對捲(R2R)塗佈製程，以不同的製程參數製備出不同的薄膜，並對於塗膜外觀之影響進行探討。此研究工作對於聚醯亞胺量產及薄膜商品化亦有很大的助益。

Polyimide (PI) is a kind of polymer material with excellent properties, such as temperature stability, solvent resistance, and high mechanical strength. PI is widely used in aerospace industry, medical industry, and electronic equipment. Among them, transparent PI films with high transparency also have advantages in the application of optical and soft electronic products. This thesis mainly uses the blade coating process technology to prepare PI films, in which the influence of the processing parameters on the characteristics and appearance of the films are discussed from the point of view of processing.
The work of this thesis can be divided into two parts. In the first part, polyamic acid precursors are used to coat with a hand-held doctor blade machine with adjustable gaps. Different polyamic acid films are prepared by changing the processing parameters. Then, PI films are formed after high temperature baking dehydration cyclization. A series of optical properties, mechanical properties, thermal properties, and appearance are analyzed and compared.
The second part is the continuous roll-to-roll coating process using the slot coating method with better coating uniformity. Different processing parameters are used to prepare different films, and the influence on the appearance of the coating films is discussed. This research work is helpful for mass production and commercialization of PI films.
