Problems solved by technology

[0010] This honeycomb porous film can solve the above problems, however, this honeycomb porous film is a film with a large number of pores, which is weak, easy to tear, and has poor handling properties
Therefore, these problems prevent its widespread use and solutions to said problems are required

Embodiment 1

[0262] On one surface of a polyethylene terephthalate film having a thickness of 200 μm, 3% by mass of 100 parts by mass of a silicone resin (SRX-211, manufactured by DowCorning Toray Co. , Ltd.) and 0.6 parts by mass of silicone resin (SRX-212, manufactured by DowCorning Toray Co., Ltd.) in toluene solution made of a mixed resin, so that the thickness after drying was 1 μm, and then the film was dried at 120 °C for 2 minutes, thereby preparing a temporary substrate having a release layer formed thereon.

[0263] Next, polystyrene having a weight-average molecular weight of 45,000 and an amphiphilic polymer having a weight-average molecular weight of 50,000 represented by the following structural formula were mixed in a mass ratio of 10:1 (polymer concentration: 0.4% by mass), thereby preparing 0.5 mL dichloromethane solution.

[0264] Next, all the dichloromethane solutions are coated on the surface of the glass substrate for HDD, and the glass substrate for HDD is kept at 2...

Embodiment 2

[0270] A honeycomb composite film was obtained in the same manner as in Example 1, except that a temporary substrate on which a release layer was formed was also bonded to the back surface of the film having a honeycomb structure. The structure of the obtained film is similar to the honeycomb composite film prepared in Example 1.

Embodiment 3

[0272] The honeycomb composite film was obtained in the same manner as in Example 1, except that a peeling layer was not formed on the back surface of the polyethylene terephthalate film having a honeycomb structure, and the peeling layer was simply heated Pressure bonded to a film with a honeycomb structure. The structure of the obtained film is similar to the honeycomb composite film prepared in Example 1.

Abstract

The object of the present invention is to provide a honeycomb composite film which contains a film having a honeycomb structure, and a provisional substrate formed on at least one surface of the film having the honeycomb structure such that the provisional substrate is exfoliatable and to provide a method for producing the honeycomb composite film which includes forming an exfoliation layer on a provisional substrate, and forming a film, the forming a film includes casting a solution containing an organic solvent and a high-polymer compound on any one of the exfoliation layer and a substrate, forming droplets in the obtained film, and vaporizing the organic solvent and the droplets to thereby produce a honeycomb-like porous film having holes in the film.

Description

technical field [0001] The present invention relates to a honeycomb composite film utilizing a honeycomb porous film prepared by self-organization, and to a method for preparing the honeycomb composite film. Background technique [0002] Recently, an increase in the degree of integration, high densification of information capacity, and high-resolution performance of image information have become more highly demanded in the fields of optical materials and electronic materials. Accompanying this trend, there is a demand for thin films used in these fields that they be formed in a fine pattern structure. In regenerative medicine technology, it is known that a thin film having a fine structure on its surface is effective as a base material to be a cell culture framework (see Japanese Patent Application Laid-Open (JP-A) No. 2001-157574). [0003] As for the above-mentioned fine pattern formation of a thin film, various methods are known, such as optical lithography technique usi...
