本研究開發利用濕式塗佈技術，將高比例顆粒懸浮溶液之磷光材料，以具有生產優勢之狹縫式塗佈技術製備電腦放射影像系統中的影像感光板。
本研究的重點在於克服粒子懸浮溶液於塗佈製程中沉澱之問題，以維持長期操作之可行性，並研發符合商業化條件產品，以提供工業化量產之參考基礎。研究的架構主要分成配方研究及製程研究兩部分，配方以參考公開專利中影像感光板之材料與合作廠商所提供之配方作結合，並以刮刀塗佈、單層狹縫式塗佈、雙層塗佈及後續滾輪輾壓乾燥等製程研究其塗佈之效果以作調整，除此之外也針對各種溶液配方之基本流體物性進行量測。
製程部分，首先以刮刀塗佈瞭解塗層成膜之基本性質，爾後利用不同單層狹縫式模具尋找適合之塗佈製程及參數條件，再嘗試製備具有一定均勻度及不同厚度之影像感光板，並以理論計算驗證狹縫式塗佈技術之可行性；再則以雙層塗佈進行多功能塗層測試，最後針對粒子堆疊進行研究，以滾輪輾壓方式測試顆粒緊密堆疊之效果。

The research is related to the manufacturing of an image plate of computed radiography(CR).
Single-layered slot die coating operation with a T-die was chosen to be a method of manufacturing of an image plate of computed radiography. Under proper control of coating parameters, phosphorescent material which is a suspensions with high solid content can form a coating layer on a PET substrate with width 10 cm. The phosphorescent coating layer has good quality after drying. The dry film thickness can be controlled in the range 100-150 μm and the uniformity can be controlled within ±10%.
