Description
本発明は、複屈折がゼロに近い耐溶剤性透明ポリイミド共重合体膜の製造に関する。より詳細には、本発明はカルボキシル基を置換基として有するポリイミド共重合体の製造および使用に関し、このポリイミド共重合体はガラス転移温度(Tg)が400℃を超える剛直な主鎖を有しながらもなお従来の有機溶媒に可溶である。このポリイミド共重合体の多官能性エポキシド含有溶液を成形することにより、400〜750nmの範囲で光透過性が高く(透過率80%超)、複屈折がゼロに近い膜が得られる。耐溶剤性は膜を約250℃以下で約30分以下にわたって加熱することにより得られる。この処理によって膜の光学的特性および熱的特性が大きく変化することはない。得られる膜は液晶ディスプレイ(LCD)や有機発光ダイオード(OLED)などのマイクロ電子デバイスおよび光電池デバイス用のフレキシブル基板として有用である。
(A)軽量(ガラス基板は1枚のフィルム太陽電池の総重量に占める割合が約98%にのぼる)。
(B)柔軟(扱いやすく、輸送コストが低く、かつ/または原材料としても製品としても用途が広い。)
(C)ロールツーロール法による製造が可能。同法を使用した場合、製造コストが大幅に削減される可能性がある。
(A)耐熱性の向上
(B)熱膨張係数(CTE)の低下
(C)高温処理時の高い透明性の維持
(D)耐溶剤性の向上、および
(E)酸素バリア性および水分バリア性の向上。
現在基板材料の候補とされている膜はいずれも十分なバリア性能を有するものではない。なお、この記述は限定要因ではなく、バリア層を新たに使用することは可能である。
