Title (EN) PIEZOELECTRIC FILM AND METHOD OF MANUFACTURING FILM
(FR) FILM PIÉZO-ÉLECTRIQUE ET PROCÉDÉ DE FABRICATION ASSOCIÉ
(JA) 圧電フィルムおよびフィルムの製造方法
Abstract:
(EN) Provided is a thin and very smooth piezoelectric film. The piezoelectric film comprises vinylidene fluoride resin as a principal component, wherein the piezoelectric film has a thickness of not more than 300 μm, and an arithmetic mean roughness Ra of not more than 0.050 μm on both sides thereof.
(FR) L'invention concerne un film piézoélectrique mince et très lisse. Le film piézoélectrique comprend une résine de fluorure de vinylidène en tant que composant principal, le film piézoélectrique ayant une épaisseur ne dépassant pas 300 µm, et une rugosité moyenne arithmétique Ra ne dépassant pas 0,050 µm sur ses deux côtés.
(JA) 薄さと高い平滑性とを備えた圧電フィルムを提供する。フッ化ビニリデン樹脂を主成分とする圧電フィルムであって、圧電フィルムの厚さが300μm以下であり、両面のそれぞれにおける算術平均粗さRaが0.050μm以下である。
