摘要： A hydrophobic liquid containing a dispersion medium and fine particles is prepared. The fine particles have insolubility of a certain level in a predetermined liquid having a hydrophobic character. The hydrophobic liquid is applied to a support to be a film thereon. Wet gas is blown to the film. Water vapor is condensed from ambient air on a surface of the film to generate water drops thereon. A dispersion medium evaporating gas is blown to the film, such that the dispersion medium is evaporated from the film. A water drop evaporating gas is blown to the film, such that the water drops are evaporated from the film. Accordingly, the water drops function as the template for forming pores, such that the pores are formed on a micro protrusion-depression structure constituted by the fine particles.

摘要： A coating liquid containing a polymer and a hydrophobic solvent is applied to a support to form a coating film. Water vapor is condensed from ambient air on a surface of the coating film. A hydrophobic solvent is evaporated until a content rate of the solvent in the coating film reaches 50 wt %. The coating film is caused to contact with liquid water. The hydrophobic solvent contained in the coating film is moved from the coating film to the water. The water and the solvent are evaporated from the coating film. Thus, a porous film having a plurality of pores is produced. It is unnecessary to adjust a surface temperature of the coating film and a dew point of the gas around the coating film precisely. It becomes possible to evaporate the hydrophobic solvent contained in the coating film rapidly.

摘要： A dipping bath contains a polymer solution. Stent body members are dipped into the polymer solution. The polymer solution forms membrane on the surface of the stent body member. Humid atmosphere is created around the stent body members with the membrane to condense water vapor into water droplets on the surface of the membrane. After growing the water droplets to water drops, a solvent is evaporated, and the water drops penetrate into the membrane. Then, the water drops are evaporated with leaving pores in the membrane. The water drops function as templates.

摘要： In a coating zone, a cylindrical tube is soaked in and taken out from a solution, such that a coating film is formed on a curved surface of the tube. In a wet gas zone, while a first gas feeding nozzle having a gas outlet moves in a state where the gas outlet faces an outer peripheral surface of the tube, wet gas is blown toward the coating film through the gas outlet. Water drops are generated on the coating film and grown up. In a dry gas zone, as in the case of the first gas feeding nozzle, while a second gas feeding nozzle having a gas outlet moves, dry gas is blown toward the coating film through the gas outlet. Solvent and water drops are evaporated from the coating film. Pores form from the water drops as a template for the porous material on the coating film.

摘要： A coating die has a discharge port for discharging a solution. A chamber has an opening. The coating die and chamber are disposed such that the discharge port and the opening are close to a support moving in an X direction. The solution is discharged through the discharge port. The discharged solution is applied to a surface of the support as a coating film. Wet air having parameters ΔTw and ΔTsolv adjusted to a predetermined range is blown through the opening to the discharged solution. The wet air contacts the solution so water vapor condenses on the surface of the solution to generate water drops. While the water drops grow up, a solvent is evaporated from the solution actively. The growth of cores of the water drops is prevented at an early stage by utilizing a decrease in fluidity of the solution due to the evaporation of the solvent.

摘要： After a second liquid is applied to a support and dried, a first liquid is applied thereon. On a film of the first liquid, a third liquid (water) is supplied in droplets using an inkjet-type liquid supply unit. An area supplied with the droplets is referred to as porous area. Next, an organic solvent is evaporated from the film and the droplets are evaporated from the porous area. Thus, a porous film is obtained. The porous film has the porous areas in which a plurality of pores are arranged. Since the droplets are directly formed by an inkjet printing method, a condensation process and a droplet growing process are unnecessary. Thus, the porous film is produced efficiently. Shapes of the porous areas can be changed easily. The porous areas can be formed on the porous film in various patterns.

摘要： A solution of polymer uniformly dissolved into a solvent is prepared in a solution preparing step. The solvent contains good and poor solvent components for the polymer. The solution is discharged from a coating die to a support to be a coating film thereon in a primary body forming step. A water drop generating step and a fluidity decreasing step are performed in parallel with each other while wet air is applied to the coating film. Water drops are generated on a surface of the coating film in the water drop generating step. The good solvent component is evaporated from the coating film to decrease fluidity of the solution for forming the coating film in the fluidity decreasing step. In the water drop evaporating step, dry air is applied to the coating film. The solvent and the water drops are evaporated from the coating film to obtain the porous film.

摘要： A second liquid is applied to a support and dried to form a middle layer. Then, a first liquid is applied to the middle layer. A third liquid is applied to a film of the first liquid using an inkjet type liquid supply unit to form a porous area. The first and third liquids differ in interfacial tension against water. Moist air is supplied to the porous area to cause condensation. In a third chamber, the condensation grows into large droplets, and a solvent is evaporated from the film. Thereafter, the droplets are evaporated from the porous area. Thus, a porous film in which a plurality of pores are arranged is produced. Since the porous area is formed by inkjet printing method, size, shape, and conditions of the porous area is easily changed.
