MEMBRANE STRUCTURE, PROCESS FOR MAKING MEMBRANE STRUCTURE AND AQUEOUS DISPERSION FOR FORMING MEMBRANE STRUCTURE
A membrane structure contains cellulose microfibers and an inorganic layered compound. The cellulose constituting the cellulose microfibers has a carboxyl content of 0.1 to 3 mmol/g. The mass ratio of the inorganic layered compound to the cellulose microfibers is 0.01 to 100. The inorganic layered c...

Summary: | A membrane structure contains cellulose microfibers and an inorganic layered compound. The cellulose constituting the cellulose microfibers has a carboxyl content of 0.1 to 3 mmol/g. The mass ratio of the inorganic layered compound to the cellulose microfibers is 0.01 to 100. The inorganic layered compound preferably has an average particle size of 0.01 to 10 µm and has an amount of charge of 1 to 1000 eq/g. The membrane structure is preferably prepared by using an aqueous dispersion containing cellulose microfibers having a carboxyl content of 0.1 to 3 mmol/g, an inorganic layered compound, and a basic substance. |
