Title:
エネルギー変換用フィルム
Document Type and Number:
Japanese Patent JP5638326
Kind Code:
B2
Abstract:
An energy conversion film, which can hold a larger amount of charges by pores in the inside of the film and has high energy conversion performances, is provided, by obtaining a porous resin film with a high expansion ratio without adopting an expansion treatment with a high-pressure gas by forming a thermoplastic resin stretched film having a specified structure. The energy conversion film (i) of the present invention is an energy conversion film (i) including a core layer (A) composed of a thermoplastic resin stretched film including a thermoplastic resin and at least one of an inorganic powder and an organic filler, wherein the core layer (A) contains pores having a height in the thickness direction of the film of from 3 to 30 µm and a diameter in the plane direction of the film of from 50 to 500 µm at a frequency of from 100 to 3,000 pores/mm 2 through the cross-sectional observation in the thickness direction. Disclosed is also an energy conversion film (i) including a core layer (A) composed of a thermoplastic resin stretched film including a thermoplastic resin and from 12 to 50% by weight of an inorganic powder or from 2 to 30% by weight of an organic filler, wherein the core layer (A) contains pores having a height in the thickness direction of the film of from 3 to 30 µm and a diameter in the plane direction of the film of from 50 to 500 µm at a frequency of from 100 to 3,000 pores/ mm 2 through the cross-sectional observation in the thickness direction.
