Description
一実施形態のポリアミック酸は二無水物化合物と、第1ジアミン化合物及び第2ジアミン化合物とを含む2種のジアミン化合物とのモル(mole)比率を1:1で維持し、溶液上で縮合重合方法に下記のような段階を経て製造された。
上述した方法に製造されたポリアミック酸をガラス基板に提供した。この時、ガラス基板はソーダ石灰ガラス(soda-lime glass、MATSUNAMI、日本国)又はホウケイ酸ガラス(borosilicate、MATSUNAMI、日本国)を使用した。ガラス基板の表面から異物質又は不純物を除去するために、超音波洗浄器(Ultrasonicator)を利用して、ガラス基板を、アセトン(acetone)内で10分間、次いで、イソプロパノール(IPA)内で約10分間、超音波洗浄した。次に、ガラス基板を17MΩ以上の超純水(DI-water)で、30分間、十分に洗浄を繰り返した後、120℃の対流式乾燥炉で60分間乾燥させた。
上述したポリアミック酸の製造及びポリイミドフィルムの製造により得られた一実施形態のポリイミドフィルムについて、光特性及び耐熱特性を評価した。一方、比較例は、ジアミン化合物を1種のみを使用したことを除くと、上述した一実施形態のポリイミドフィルムを製造する方法と同一の方法でポリイミドフィルムを製造したものである。
