Abstract
An ion complex which comprises a water-insoluble polyion (P) and a water-soluble polyion (A); and is insoluble in water and soluble in an aqueous organic solvent. Such an ion complex becomes a coating material which can preferably be used for coating of various ionic substances (e.g., substance having biological activity such as an anticoagulant property or an antibacterial property).
Claims15
An ion complex comprising a water-insoluble polyion (P) and a water-soluble polyion (A);
- the ion complex being insoluble in water and soluble in an aqueous organic solvent.
A coated product comprising a material to be coated, and a coating layer covering at least a portion of the surface of the material to be coated,
- wherein the coating layer comprises an ion complex which comprises a water-insoluble polyion (P) and a water-soluble polyion (A);
- and is insoluble in water and soluble in an aqueous organic solvent.
A coating method comprising:
- applying a solution comprising an aqueous organic solvent and an ion complex dissolved in the solvent on a material to be coated;
- and
- evaporating the aqueous organic solvent to form a coating on the material to be coated;
- wherein the ion complex comprises a water-insoluble polyion (P) and a water-soluble polyion (A);
- and the ion complex is insoluble in water and soluble in an aqueous organic solvent.
A coating method comprising:
- attaching at least an ion complex in the form of powder to a material to be coated;
- swelling the ion complex with an aqueous organic solvent;
- and
- evaporating the aqueous organic solvent to form a coating;
- wherein the ion complex comprises a water-insoluble polyion (P) and a water-soluble polyion (A);
- and the ion complex is insoluble in water and soluble in an aqueous organic solvent.
