Abstract
Official abstract text for this publication.
Disclosed is a molded article including a modified fibroin and a water resistance-imparting material. The modified fibroin and the water resistance-imparting material may be covalently bonded.
First claim
Opening claim text (preview).
The invention claimed is: 1. A molded article, comprising: a modified fibroin; and a water resistance-imparting material, wherein the modified fibroin and the water resistance-imparting material are covalently bonded, and the water resistance-imparting material is at least one selected from a silicone-based polymer and a fluorine-based polymer. 2. The molded article according to claim 1 , wherein the modified fibroin is a modified spider silk fibroin. 3. The article according to claim 1 , wherein the molded article is a fiber. 4. A method for producing a molded article, the method comprising a step of covalently bonding a water resistance-imparting material to a precursor molded article comprising a modified fibroin, wherein the water resistance-imparting material is at least one selected from a silicone-based polymer and a fluorine-based polymer. 5. The method according to claim 4 , wherein the step of bonding the water resistance-imparting material to the precursor molded article includes irradiating the precursor molded article with plasma in a state in which the water resistance-imparting material or a precursor of the water resistance-imparting material is brought into contact with the precursor molded article, and thereby covalently bonding the modified fibroin and the water resistance-imparting material. 6. The method according to claim 4 , wherein the water resistance-imparting material is at least one selected from a silicone-based polymer and a fluorine-based polymer. 7. The method according to claim 4 , wherein the modified fibroin is a modified spider silk fibroin. 8. The method according to claim 4 , wherein the molded article is a fiber. 9. A method for producing a molded article, the method comprising a step of molding a raw material containing a modified fibroin and a water resistance-imparting material and thereby obtaining a molded article, wherein the water resistance-imparting material is a modified hydroxyl group-containing polymer formed as a result of a hydrophobic functional group being bonded to a hydroxyl group-containing polymer. 10. The method according to claim 9 , wherein the molded article is a fiber.
