Document Type and Number:
Japanese Patent JP7113449
Kind Code:
B2
Abstract:
To provide a method which can efficiently produce a collection substance containing a nanocellulose composite (pseudo complex), and to provide a method which can produce a sheet-like collection substance.SOLUTION: There is provided a method for producing an adsorptive foam comprising a composite (pseudo complex) formed from an adsorbent capable of adsorbing and retaining a target substance and nanocellulose. The method for producing the adsorptive foam includes: a raw material preparation step of obtaining a liquid raw material mixture containing an aqueous liquid dispersion medium, a water dispersible resin, a crosslinking agent, a foaming agent, and the composite (pseudo complex) formed from the adsorbent capable of adsorbing and retaining the target substance and the nanocellulose; a foaming step of mechanically foaming the liquid raw material mixture to obtain a foaming mixture; a forming step of forming the foaming mixture into a sheet on a substrate; and a drying step of heating the foamed mixture formed into a sheet and evaporating the dispersion medium.SELECTED DRAWING: None
