Abstract
【解決手段】
少なくとも1つの分極性官能基を有する溶媒、および沈殿剤を使用する、強誘電体、好ましくはフッ化ビニリデンポリマーの分別方法が提供される。分別された強誘電性ポリマーの組成は、該ポリマーから調製される強誘電性フィルムの特性を調整するように選択される。分別されたフッ化ビニリデンポリマーを使用して形成されたフィルムは、特に粗さおよび結晶ドメインサイズに関して改良された特性を有し、しかもデータ処理デバイスに使用するための適合性を有する。
【選択図】なし
Description
ポリ(フッ化ビニリデン−co−トリフルオロエチレン)(78モル%/22モル%)を、Solvay Corporationから入手した。このポリマー約1重量%をアセトニトリルに溶解した。水を溶液に溶液が混濁するまで加えた。この溶液を次いで、混濁溶液が透明になるまで約45℃に加熱した。この加熱溶液を分液ろうとに移し、断熱チャンバー中で白熱電球と、温度を維持するための温度制御装置とを使用して室温よりも1〜3℃高い一定温度で一夜保持した。約14時間後に、濃厚な画分が分液ろうとの底に形成された。この画分を取り出し、透明画分(すなわち、母液)をさらに抽出するためにフラスコに移した。濃厚な分別されたポリマー部分を減圧下で乾燥し、得られた画分の分子量と分子量分布を、テトラヒドロフランを溶出液として使用し且つ蒸発光散乱検出を使用してゲル透過クロマトグラフィーにより測定した。この方法により得られた画分の分子量分布は1.07であった。
