Description
超薄膜ブラックポリイミドフィルムの製造(厚さ7.5μm)
ポリアミック酸溶液重合工程であって、300L反応器に窒素雰囲気下で溶媒としてN,N’-ジメチルホルムアミド(DMF)を733.5g投入した。温度を25℃にして、ジアミンとして4,4'-ジアミノフェニレンエーテル(ODA)63.25g及び1,4-フェニレンジアミン(PPD)11.39gを入れた。30分ほど攪拌し単量体が溶解されたことを確認してからピロメリット酸二無水物(PMDA)を91.86g投入した。投入が終わると温度を維持しながら1時間攪拌してポリアミック酸溶液を重合した。
超薄膜ブラックポリイミドフィルムの製造(厚さ7.5μm)
下記表1に記載された第1カーボンブラック及び第2カーボンブラックの平均粒径及び含量を使用したことを除いては、実施例1と同一の方法で厚さ7.5μmの超薄膜ブラックポリイミドフィルムを製造した。
超薄膜ブラックポリイミドフィルムの製造(厚さ5μm)
下記表2に記載された第1カーボンブラック及び第2カーボンブラックの平均粒径及び含量を用い、SUS plateにドクターブレードを使用して50μmにキャストすることを除いては、実施例1と同一の方法で厚さ5μmの超薄膜ブラックポリイミドフィルムを製造した。

光沢の評価
光沢度測定装備(モデル名:E406L、製造社:Elcometer)で60°の角度でASTMD523の方法で測定した。
透過率の評価
透過率測定機器(モデル名:ColorQuesetXE、製造社:HunterLab)を用いて可視光領域においてASTMD1003の方法で透過度を測定した。
寸法安定性の評価-熱膨張係数(CTE)
熱分析器(モデル名:Q400、製造社:TA)を用いて0.05Nの圧力下で10℃/分の速度で400℃まで昇温させた後、さらに10℃/分の速度で40℃まで冷却させた。その後、10℃/分の速度で400℃まで昇温させながら、昇温区間中の100〜200℃区間の傾きを測定した。
