摘要： To provide a method for manufacturing a flow path device internally provided with a flow path for allowing a liquid to flow by compression bonding two or more members to each other, wherein the hydrophilic property of a surface of the flow path can be maintained for a long period of time. A flow path device is manufactured by forming a hydrophilic coating film using a treatment liquid including a hydrophilizing agent in at least one member of the members, the coating film covering a surface of the member at a side to be joined to another member, then irradiating only a joining surface of the hydrophilic coating film with ultraviolet rays or plasma derived from an oxygen-containing gas in the member having the hydrophilic coating film, and irradiating at least the joining surface with ultraviolet rays or plasma derived from an oxygen-containing gas in a member having no hydrophilic coating film, and compression bonding the two or more members having been subjected to such treatment.

摘要： An object is to provide a hydrophilic treatment method which can firmly bond, while coating the surface of a treatment target with an extremely thin film, the coating to the surface of the treatment target and a surface treatment liquid which can be suitably used in the hydrophilic treatment method. In a hydrophilic treatment method using a surface treatment liquid containing a resin (A) and a solvent (S), the surface treatment liquid which includes, as the resin (A), a constituent unit (a1) derived from an N-substituted (meth) acrylamide having a hydrophilic group, which contains, in at least one of molecular chain terminals, a resin including a reactive silyl group and pH of the liquid is 4 or less is used, and thus a coating is formed on the surface of a treatment target.

摘要： An object is to provide a surface treatment liquid which can firmly bond, while coating the surface of a treatment target with an extremely thin film, a coating whose hydrophilicity is unlikely to be lowered even when the coating is brought into contact with fats and the like to the surface of the treatment target and a surface treatment method using the surface treatment liquid described above. In a surface treatment liquid containing a resin (A) and a solvent (S), as the resin (A), a resin is used which includes a constituent unit (a1) that includes an organic group including a quaternary ammonium cation group and having a sulfonic acid anion group at a terminal and that is derived from an N-substituted (meth) acrylamide, and includes a reactive silyl group in at least one of molecular chain terminals, the concentration of the resin (A) in the surface treatment liquid is less than 2 mass% and the pH of the surface treatment liquid is 4 or less.

摘要： To provide a surface treatment liquid capable of making a base material including polyorganosiloxane on at least a part of a surface thereof hydrophilic stably over a long period of time, and provide a surface treatment method using the surface treatment liquid. In a surface treatment liquid including (A) resin and a (B) solvent, as the (A) resin, resin having a functional group I that is a hydroxyl group and/or a cyano group is used, and a functional group II that is a hydrophilic group other than the functional group I, and a ratio of a structural unit having an anionic group to total structural units of the (A) resin is 5 mol% or less, or resin including a cationic group including an anion moiety and a cation moiety that can be bonded to the (A) resin is used.

摘要： To provide a surface treatment method capable of successfully making a treatment target including polyimide on a surface thereof hydrophilic or hydrophobic with a safe operation; a two-liquid type surface treatment liquid that can be suitably used for the surface treatment method; and a surface-treated polyimide product that can be obtained by the above-described surface treatment method. A first resin having a primary amino group and/or a hydroxyl group, and a secondary amino group is bonded to a surface of a treatment target including polyimide on a surface thereof, and then a second resin having a (meth)acryloyl group and/or a carbamoyl group, a hydrophilic group and/or a hydrophobic group is bonded to the first resin.
