Abstract: The present invention relates to a method for manufacturing a photo-responsive cross-linked liquid-crystalline polymer film, containing: a process of preparing a photopolymerizable monomer solution by dissolving in a solvent a polyfunctional liquid-crystalline monomer, a monofunctional liquid-crystalline monomer, a polyfunctional photo-responsive monomer and a photopolymerization initiator; a process of forming a photopolymerizable coating by applying the photopolymerizable monomer solution to a surface of an alignment film by means of a wet coating method and performing removal of the solvent; and a process of forming a film by photopolymerizing the monomers through light irradiation of the photopolymerizable coating under a non-oxygen atmosphere.

Abstract: A soundproof structure includes a porous fibrous body that attenuates incident sound waves, wherein the fibrous body is formed of fibers having an average fiber diameter of 0.5 μm or more and 5 μm or less, and includes a surface layer on which the sound waves are incident and a propagation layer that is stacked with the surface layer and that propagates the sound waves from the surface layer, and wherein the propagation layer includes a high density layer having a density higher than a density of the surface layer.
