Abstract: A molding device produces a porous film from a molding material which is an emulsion. In a case where a volume of a dispersed phase is X1 and a volume of a continuous phase is X2, the molding material has a value of X1/(X1+X2) within a range of 0.5 or more and 0.9 or less. In the molding material, a specific gravity of the dispersed phase is greater than a specific gravity of the continuous phase. The molding material includes a water phase containing a curable compound as the continuous phase, and forms a liquid film on a support. Thereafter, the curable compound in the liquid film is cured. After curing, the dispersed phase is removed.

Abstract: A protrusion/recess structure in which fine particles will not drop easily and which will not be deformed easily is provided, and a producing method for the same is provided. In the protrusion/recess structure (porous film), protrusions or recesses (fine corrugations) are formed in a surface. The protrusion/recess structure is formed from plural fine particles and an amphipathic high molecular compound having a catechol group. The high molecular compound at least partially coats a surface of the fine particles, to adhere the fine particles to one another. A diameter of the recesses is larger than a diameter of the fine particles. Cast film is formed from solution containing the fine particles and the high molecular compound having the catechol group. Condensation on the cast film is performed, and organic solvent and water droplets created by the condensation are evaporated to produce the protrusion/recess structure.

Abstract: Disclosed is a film which is able to suppress agglutination by being continuously adhered to an adhesion target portion in a biological body while suppressing a position shift. A film includes an adhesive and an adhesion inhibiting layer. The adhesive layer absorbs and maintains a liquid in a plurality of pores which are opened in one film surface and has a capillary force for adhering the adhesive layer to a first-cell group. The adhesive layer is formed of a biodegradable polymer. The adhesion inhibiting layer configures the other film surface, and inhibits adhesion between a second-cell group which is different from the first-cell group and the adhesive layer. In the adhesive layer, the pore is formed not to be penetrated in a thickness direction of the film, and thus the first-cell group and the second-cell group are separated into the one film surface side and the other film surface side.

Abstract: A molded body is produced from a molding material including a continuous phase and a dispersed phase by a three-dimensionalization step, a curing step, and a peeling step. The continuous phase of the molding material is a water phase containing a curable compound. In the three-dimensionalization step, the molding material is placed in a container. In the curing step, the curable compound is cured to form a cured product after the three-dimensionalization step. In the peeling step, the container and the cured product are separated after the curing step. In the dispersed phase removal step, the dispersed phase of the cured product is removed after the curing step.
