以下、本発明による実施例及び本発明によらない比較例を通じて本発明をさらに詳しく説明するが、本発明の範囲が下記提示された実施例によって制限されるものではない。
1.接着剤溶液の製造
水分吸着剤としてCaO(Aldrich)70gをメチルエチルケトンに30wt%の濃度で投入して水分吸着剤溶液を製造し、前記溶液をボールミル工程によって24時間ミーリングした。また、これとは別に、常温で反応器にシラン変性エポキシ樹脂(KSR−177、KUKDO化学)200g及びフェノキシ樹脂(YP−50、DONGDO化成)150gを投入し、メチルエチルケトンで希釈した。その後、反応器の内部を窒素で置換し、製造された溶液を均質化した。前記均質化された溶液にあらかじめ準備した水分吸着剤溶液を投入し、硬化剤であるイミダゾール(四国化成)4gを投入した後、1時間高速撹拌し、接着剤溶液を製造した。
前記で準備しておいた接着剤溶液を離型PETの離型面にコンマコーターを用いて塗布し、乾燥器で130℃に3分間乾燥し、厚さが15μmの接着層を形成した後、接着層の上部に離型PETをさらに圧着した。
前記で準備した接着フィルムを−5℃の温度でそれぞれ2週、4週及び8週間冷凍保管した。
前記実施例1の接着フィルム保管過程で保管温度を4℃の温度で冷蔵保管したことを除いて実施例1〜3と同様の方法で接着フィルムを製造した。
実施例1〜3及び比較例1〜3の接着フィルムに対する貯蔵温度及び保管期間による水分遮断特性を照射するために、カルシウムテストを進行した。具体的には、100mm×100mmサイズのガラス基板上にカルシウム(Ca)を5mm×5mmのサイズ及び100nmの厚さで9個(9 spot)蒸着し、実施例1〜3及び比較例1〜3の接着フィルムが転写されたカバーガラスを各カルシウム蒸着箇所に真空プレス(vacuum press)を使用して、80℃で1分間加熱圧着した。その後、高温乾燥器内で100℃に3時間硬化させた後、11mm×11mmのサイズで封止されたカルシウム(Ca)試験片をそれぞれ切断した。得られた試験片を恒温恒湿チャンバで85℃の温度及び85%R.H.の環境に放置した後、水分浸透による酸化反応によってカルシウムが透明になり始めた時点を評価し、下記表1及び表2に示した。
実施例1〜3及び比較例1〜3の接着フィルムの重さ増加率を照射した。具体的には、実施例1〜3及び比較例1〜3の接着フィルムを200μmの厚さで製造した後、高温乾燥器内で100℃に3時間硬化させた後、5cm×5cmでカットして試験片を製造した。前記硬化された試験片の初期重さを記録した後、前記試験片を恒温恒湿チャンバで85℃の温度及び85%R.H.の環境に24時間放置した後、表面の水分を除去し、重さを測定した。試験片の重さ増加率を下記のように計算し、下記表2に示した。
前記式で、Bは、水分吸収後の試験片の重さであり、Aは、試験片の初期重さである。
実施例1〜3及び比較例1〜3の接着フィルムの保管前後の水分遮断能力の変化を測定するために、接着フィルム内部の水分吸着剤(CaO)の純度の変化をX線回折(X−ray Diffraction、XRD)分析法で測定した。具体的に、XRD機器(Bruker AXS D4 Endeavor XRD(2))を使用して40kVの電圧と40mAの電流値でCu Kα radiationの波長を1.5418ÅにしてCaOの固有値2theta 10度で100度領域を0.019度ごとに175秒ずつ測定し、図1に示し、図1を参照すれば、CaOと水分反応後Ca(OH)2は、それぞれ異なる比率を有する。それぞれの接着フィルムのCaOの純度値の変化を測定するためにリトベルト構造検証(Rietveld refinement)を行った後、CaO及びCa(OH)2の重量比(wt%)を計算し、下記表3に示した。
