Description
前記芳香族ジアミン成分100モル%中、2,4−トルエンジアミンが3モル%以上35モル%未満の範囲で含まれることを特徴とするポリイミドフィルム。
3,3’,4,4’−ビフェニルテトラカルボン酸二無水物から主として成る芳香族テトラカルボン酸成分と、65モル%以上97モル%未満のパラフェニレンジアミンおよび3モル%以上35モル%未満の2,4−トルエンジアミンから成る芳香族ジアミン成分とから得られるポリイミド前駆体の溶液を支持体上に流延塗布し、加熱してポリイミド前駆体溶液の自己支持性フィルムを製造する工程と、
この自己支持性フィルムを加熱、イミド化する工程と
を有するポリイミドフィルムの製造方法。
また、上記の自己支持性フィルムのイミド化率は、IR(ATR)で測定し、フィルムとフルキュア品との振動帯ピーク面積または高さの比を利用して、イミド化率を算出することができる。振動帯ピークとしては、イミドカルボニル基の対称伸縮振動帯やベンゼン環骨格伸縮振動帯などを利用する。またイミド化率測定に関し、特開平9−316199号公報に記載のカールフィッシャー水分計を用いる手法もある。
フィルムをIEC450規格のダンベル形状に打ち抜いて試験片とし、ORIENTEC社製TENSILONを用いて、チャック間30mm、引張速度2mm/minで、初期弾性率、破断強度、破断伸びを測定した。
自己支持性フィルムと、そのフルキュアフィルム(ポリイミドフィルム)のFT−IRスペクトルを、ニコレー製Magna550FT−IRを用いて、Geクリスタル、入射角45°のATR法で測定し、1775cm−1のイミドカルボニル基の非対称伸縮振動のピーク高さと1515cm−1の芳香環の炭素−炭素対称伸縮振動のピーク高さの比を用いて、次式によりイミド化率を算出した。
(3)自己支持性フィルムの加熱減量
自己支持性フィルムの質量W1とキュア後のフィルムの質量W2とから次式によって求めた。
(4)自己支持性フィルムの表面平滑性
自己支持性フィルムの表面平滑性は目視観察により判断し、均一な平滑面ではなく、模様や段差が見られるものを×、見られないものを○とした。
ポリイミドフィルムの発泡、粉化の有無は目視観察により判断し、発泡、粉化が見られるものを×、見られないものを○とした。
エスアイアイ・ナノテクノロジー株式会社製TMA/SS6100を用いて、試験片幅4mm、測定長15mm、荷重2gまたは4g、10℃/minで室温から350℃まで昇温した。そして、得られたTMA曲線から、50℃から200℃までの平均熱膨張係数を求めた。
得られたフィルムを150℃で3時間真空乾燥して、乾燥質量W0を測定した。その後、フィルムを23℃の水に浸漬して24時間静置した。フィルム表面に付着した水をろ紙で拭き取り、吸水後の質量W1を測定して、吸水率を数式(1)から求めた。
(8)ポリイミドフィルムの吸水膨張係数(CHE)
フィルムの60mm×60mmの領域に約30mm間隔で格子状に浅い線をカッターで入れ、150℃で3時間真空乾燥した。カッターで入れた線と線の交点を格子点として、この乾燥膜の格子点間隔L0を、ニコン製測定顕微鏡MM−40を用いて、1μm単位で記録した。その後、フィルムを23℃の水に浸漬して24時間静置した。フィルム表面に付着した水をろ紙で拭き取り、吸水後の格子点間隔L1をL0と同様に記録して、吸水膨張係数を数式(2)により計算した。試験片1つにつき、MD,TD各々3間隔のCHEを平均し、さらに、一種類につき試験片3つの平均値とした。
・・・数式(2)
(9)ポリイミドフィルムの吸水速度
得られたポリイミドフィルムを150℃で3時間真空乾燥して、乾燥質量W0を測定した。次いで、23℃、50RH%の環境下でフィルムを静置して、時間t後の質量Wtを測定する。そして、数式(3)に従い、時間tでの吸水率Ctを算出する。
同様にして飽和に達するまで経時的に質量を複数測定して、t0.5/LとCt/Ceをプロットして得られる曲線の初期の直線部分の傾き(4D0.5/π0.5)から吸水の拡散係数Dを算出した。
ここで、Lは膜厚、tは時間、Dは拡散係数、Ctは時間tの吸水率、Ceは23℃、50RH%での飽和時の吸水率を表す。
得られたポリイミドフィルムを2cm×2mmの短冊状に切り取って試験片とし、ティー・エイ・インスツルメント社製RSAIIIを用いて、引張モードで固体粘弾性測定を行った。窒素気流下、室温から限界温度まで3℃/stepで昇温しながら、10Hzで測定し、得られたE’の曲線から400℃の弾性率を求めた。また、E’’曲線の極大からガラス転移温度(Tg)を求めた。
得られたポリイミドフィルムに、株式会社有沢製作所製カバーレイCVA0525KAを180℃、3MPaで30分プレスして貼り合わせた。そして、50mm/分の剥離速度で90°ピール強度を測定し、接着強度とした。なお、ポリイミド前駆体溶液をガラス板または金属支持体上にキャスティングしたときの空気側の面をA面、ガラス板または金属支持体側の面をB面とした。
得られたポリイミドフィルムに、デュポン株式会社製アクリル系接着剤(パイララックスLF0100)、日鉱金属株式会社製圧延銅箔(BHY−13H−T、18μm厚)を重ね合わせ、プレスにて、180℃、9MPaで5分圧着、さらに、180℃で60分熱処理して積層板を得た。そして、JIS・C6471−8.1に従って、50mm/分の剥離速度で90°ピール強度を測定し、接着強度とした。なお、ポリイミド前駆体溶液をガラス板または金属支持体上にキャスティングしたときの空気側の面をA面、ガラス板または金属支持体側の面をB面とした。
