Title:
PRODUCTION METHOD FOR FILM HAVING HONEYCOMB STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/132819
Kind Code:
A1
Abstract:
[Problem] To produce a film having a honeycomb structure exhibiting highly-precise pattern regularity. [Solution] A method comprising, in sequence: a water layer formation step for preparing a substrate (30), at least the front surface of which is a light-absorbing heat-generating body having a plurality of recesses or through holes that are capable of retaining water, and forming a water layer (20) within the plurality of recesses (30p) or through holes (32); a polymer solution layer formation step for bringing a polymer solution, obtained by dissolving at least an amphipathic polymer in a hydrophobic organic solvent, into contact with the front surface of the substrate (30) in which the plurality of recesses (30p) or through holes (32) were formed, and forming a polymer solution layer (10) on the front surface; a water droplet formation step for irradiating a prescribed two-dimensional array position on the front surface or the back surface of the substrate (30) with a light spot (L) so as to cause the irradiated site of the light-absorbing heat-generating body to generate heat and thereby form water droplets (20b) within the polymer solution layer (10) in the vicinity of the contacted substrate surface; and a vaporization step for vaporizing the water droplets (20b) and the hydrophobic organic solvent to form a polymer layer (11) including at least the amphipathic polymer, and a plurality of pores (12) in one surface of the polymer layer (11).
