Method for producing functional material, functional material, sheet-like structure and sanitary product

摘要

Provided is a method for producing a functional material, including the steps of: bringing a polyvalent metal cation aqueous solution into contact with a base material; bringing a polyanion aqueous solution containing a functional component into contact with the base material previously in contact with the polyvalent metal cation aqueous solution to bond the polyvalent metal cations and the polyanions to each other, and thereby forming an insoluble compound containing the functional component; and drying the base material including the insoluble compound.

主权项

1. A functional material produced by drying a base material including an insoluble compound containing a functional component, the insoluble compound being formed by bringing a polyanion aqueous solution containing the functional component into contact with the base material including a polyvalent metal cation aqueous solution, to bond the polyvalent metal cations and the polyanions to each other,
wherein the polyanion aqueous solution includes sodium alginate; a concentration of the polyanion solution is from 0.05% by weight or more to less than 0.2% by weight; a concentration of polyvalent metal cation aqueous solution is within a range of 0.25% by weight to 0.5% by weight; and a molar ratio of the sodium ions contain in the polyanion aqueous solution to the sodium ions contained in the polyvalent metal cation aqueous solution is 1:5 to 1:10.
