Abstract
【解決手段】ナノまたはマイクロサイズの粒子を溶融状態のポリマーマトリックスに均一に分散させ、均一に分散された溶融状態のポリマーを平板状に作り、これを二つの押出しローラーの間で押し出して成形することにより、粒子を薄膜表面に平行に配向させ、続いて、シートをガラス転移温度と溶融点の間で延伸してフィルム(薄膜)を成形することにより、粒子の剥離を促進させ、粒子を薄膜表面にさらに平行に配向させる。さらに、有機コーティングによってフレキシブル基板の表面を平坦化、有機膜の硬化のための熱処理段階を行う。なお、粒子は板状構造を持つ物質であり、粒子はSi、B、Li、Na、K、Mg、Ca、Ti、Al、Ba、Zn、Ga、Ge、Bi、及びFeの中で少なくとも1種の元素を含む。
