제목 A Novel Window Cover Film Based on Functional Polyimide With Fluorinated Urea Oligomer for Flexible Displays
초록 A novel transparent polyimide based on fluorinated urea oligomer is synthesized and its optical and mechanical properties are examined. The fluorinated urea oligomer with amine groups at both ends is synthesized and reacted with 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA) and 4,4'-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) to prepare the fluorinated polyimide with urea oligomer (uoFPI). 2,2'-bis(trifluoromethyl)-[1,1'-biphenyl]-4,4'-diamine (TFDB), BPDA, and 6FDA are polymerized to prepare conventional fluorinated polyimide (cFPI) as a reference. Interestingly, uoFPI shows more outstanding optical and mechanical properties than cFPI owing to the unique supramolecular network. This results from the strong interaction between urea oligomeric blocks and imide groups in the uoFPI chains where urea groups are serially connected in urea blocks.
