摘要： A film of the present invention contains a polypeptide derived from spider silk proteins. The decomposition temperature of the film is 240 to 260°C. The film absorbs ultraviolet light having a wavelength of 200 to 300 nm and has a light transmittance of 85% or more at a wavelength of 400 to 780 nm. The film is transparent and colorless in a visible light region. A method for producing a film of the present invention includes: dissolving a polypeptide derived from spider silk proteins in a dimethyl sulfoxide solvent to prepare a dope; and cast-molding the dope on a surface of a base. Thus, the present invention provides a spider silk protein film that can be formed easily and has favorable stretchability, and a method for producing the same.

摘要： An artificial polypeptide fiber of the present invention is an artificial fiber containing a polypeptide as a main component, and has a stress of 350 MPa or more and a toughness of 138 MJ/m 3 or more. A method for producing an artificial polypeptide fiber of the present invention is a method for producing the artificial polypeptide fiber obtained by spinning a spinning solution (6) containing a polypeptide derived from natural spider silk proteins and performing drawing of at least two stages. The drawing of at least two stages includes a first-stage drawing (3) in wet heat and a second-stage drawing (4) in dry heat. Thereby, the present invention provides high-toughness artificial polypeptide fibers having favorable stress and rupture elongation, and a method for producing the same.
