Publication number: 20150065597Abstract: Disclosed is a method for producing a porous polymer film. This method includes the steps of: (I) irradiating a polymer film with an ion beam of accelerated ions so as to form a polymer film that has collided with the ions in the beam; and (II) chemically etching the polymer film formed in the step (I) so as to form openings and/or through holes corresponding to tracks of the colliding ions left in the polymer film. In the step (I), the polymer film is placed in an atmosphere with a pressure of 100 Pa or more, and the polymer film placed in the atmosphere is irradiated with the ion beam that has passed through a beam line maintained at a lower pressure than the pressure of the atmosphere and through a pressure barrier sheet disposed at an end of the beam line to separate the beam line from the atmosphere.Type: ApplicationFiled: March 27, 2013Publication date: March 5, 2015Inventors: Satoru Furuyama, Junichi Moriyama, Yozo Nagai, Yosuke Yuri, Ikuo Ishibori, Takahiro Yuyama, Tomohisa Ishizaka, Susumu Okumura, Yasunari Maekawa, Hiroshi Koshikawa, Tetsuya Yamaki, Masaharu Asano
