Abstract:
(EN) A polypropylene film which has a crystallite size of not more than 12.2 nm, said crystallite size being determined using the Scherrer equation from the half value width of a reflection peak in the α crystal (040) plane that is measured by the wide-angle X-ray diffractometry, and a volume resistivity of not lower than 6×1014 Ω·cm, said volume resistivity being calculated in accordance with equation I from a current value that is measured 1 minute after applying a voltage at a potential gradient of 200 V/μm in an environment at 100°C. Equation I: volume resistivity = [(effective electrode area) × (applied voltage)] / [(polypropylene film thickness) × (current value)].
(FR) L'invention concerne un film de polypropylène qui présente une dimension de cristallite ne dépassant pas 12,2 nm, ladite dimension de cristallite étant déterminée à l'aide de l'équation de Scherrer à partir de la largeur à mi-hauteur d'un pic de réflexion dans le plan cristallin α (040) qui est mesuré par diffractométrie des rayons X à grand angle, et une résistivité volumique non inférieure à 6×101 4 Ω·cm, ladite résistivité volumique étant calculée conformément à l'équation I à partir d'une valeur de courant qui est mesurée 1 minute après l'application d'une tension à un gradient de potentiel de 200 V/μm dans un environnement à 100°C. Équation I : résistivité volumique = [(surface effective d'électrode) × (tension appliquée)]/[(épaisseur de film de polypropylène) × (valeur de courant)].
(JA) 広角X線回折法で測定されるα晶(040)面の反射ピークの半価幅からScherrerの式を用いて求められる結晶子サイズが12.2nm以下であり、100℃環境下において電位傾度200V/μmで電圧を印加し、1分経過時点の電流値から式Iにより算出される体積抵抗率が6×1014Ω・cm以上であるポリプロピレンフィルム。ここで、式Iは、体積抵抗率=[(有効電極面積)×(印加電圧)]/[(ポリプロピレンフィルムの厚さ)×(電流値)]。
