【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、高い誘電率をもった高分子フィルムに関
し、詳しくは金属錯体を含有したフッ化ビニリデン共重
合体から成る高分子フィルムに関する。Description: TECHNICAL FIELD The present invention relates to a polymer film having a high dielectric constant, and more particularly, to a polymer film comprising a vinylidene fluoride copolymer containing a metal complex.
一般に、高分子フィルムの誘電率は３〜10程度であ
り、利用目的によってはより高い誘電率が要求される。Generally, the dielectric constant of a polymer film is about 3 to 10, and a higher dielectric constant is required depending on the purpose of use.
従来、高分子フィルムの誘電率を高めるために種々の
方法が採用されている。例えば、（１）高分子物質に高

ン性不純物を添加すると、伝導率の増加にともない低周
波域で電極分極のため誘電率が増加する。Conventionally, various methods have been adopted to increase the dielectric constant of a polymer film. For example, (1) when a high dielectric constant crystal or conductive powder is mixed with a polymer substance, the dielectric constant increases over a wide frequency band. (2) When an ionic impurity is added to a polymer substance, the dielectric constant increases due to electrode polarization in a low frequency region with an increase in conductivity.

い。又、（２）の方法では、伝導率が増加するため、誘
電率の増加の利点がない。In the conventional method (1), it is necessary to mix a large amount of powder to lose the flexibility of the polymer in order to increase the dielectric constant by one digit or more. However, in the case of conductive powder, if mixed in a large amount, it becomes conductive as a whole, and the original purpose is not achieved. In the method (2), since the conductivity increases, there is no advantage in increasing the dielectric constant.

ことにより、極めて大きな誘電緩和現象を見出した。The present inventors have found an extremely large dielectric relaxation phenomenon by combining a vinylidene fluoride (VDF) / ethylene trifluoride (TrFE) copolymer with a metal complex dye.

る。Although the mechanism of the large dielectric relaxation phenomenon in the present invention has not been elucidated, one possibility is that a Maxwell-Wagner type due to the dispersion of a dye having a high dielectric constant in the copolymer is considered. However, it was difficult to think that the extremely large relaxation strength of over 500 was attributable to the effect of simply dispersing the pigment particles. A large relaxation phenomenon is exhibited, and it is possible that a large dielectric constant is obtained.

る。According to the present invention, the addition of several percent of a metal complex dye increases the dielectric constant by one digit or more without increasing the conductivity in a specific frequency band, so that the polymer film has a high dielectric constant and low loss in a specific frequency range. It can be used for small capacitors.
