Description
また、分子量が60万/mol未満であると、圧電膜の耐変形性が低下する不具合が生ずる。
前記圧電膜は、基板に塗布して、乾燥し、前記乾燥して形成した共重合体の膜を140℃以上から150℃以下の温度範囲にて熱処理し、結晶化して、圧電特性を発生させている。
図1は、圧電膜の製造方法の工程フロー図である。圧電膜の製造工程は、調液工程→塗布工程→乾燥工程→熱処理、結晶化→電極形成→分極の順番にて実施され、P(VDF/TrFE)圧電膜が作製される。
調液工程
フッ化ビニリデン(VDF)と、トリフルオロエチレン(TrFE)との共重合体と、溶媒(DMF)との溶液を作製する。
塗布工程
基板となるPET基材を準備し、前記PET基材の上に、前記溶液を塗布する。常温での乾燥時の塗布膜の厚みは、50μmである。
乾燥工程
ホットプレートを使用し、80℃、1時間、ドラフト内で、大気下にて、塗布された膜を乾燥する。
熱処理、結晶化
オーブンにて、140℃以上から150℃以下の温度範囲にて膜を熱処理し、結晶化し、圧電特性を発生させる。
電極形成
抵抗加熱式の真空蒸着機を使用し、気圧1〜3×10-5Paの範囲にてアルミを加熱蒸発させ、膜の両面に電極被膜を形成する。
分極
分極処理は、膜をシリコンオイル中に配置し、膜両面の電極間に直接、振幅120MV/m、周波数50mHzの三角波を5周期以上印加し行う。
表1は、実施例(発明品1,2)の圧電膜の、引張り強さ、破断歪み、弾性率の数値と、比較例(1,2,3)の圧電膜の、引張り強さ、破断歪み、弾性率の数値との比較一覧表を示す。
図3は、圧電膜(P(VDF/TrFE)の各配合比の試料に関する、熱特性である。図3にて、圧電膜のVDF/TrFEの比率が、59/41,75/25,81/19の試料では、141℃以下にキュリー点に相当する吸熱ピークが存在している。
注) キュリー点
圧電性を示す強誘電相から、圧電性を示さない常誘電相への相転移温度一方、圧電膜のVDF/TrFEの比率が、85/15である2つの試料に関しては、融点である159℃までキュリー点に相当する吸熱ピークが無い。この結果より、圧電膜のVDF/TrFEの比率が85/15の試料は、高温耐熱性が優れていることが確認された。
