Abstract
The present invention includes membranes comprising one or more cellulosic materials and wetting agent(s), and methods of making such membranes.
Claims33
A membrane comprising a porous matrix material, wherein the porous matrix material comprises:
- (i) wood pulp;
- (ii) cellulose nanofilbrils (CNF);
- and
- (iii) one or more wetting minerals.
1 more element
A method comprising:
- (i) providing slurry comprising wood pulp and water;
- (ii) mixing cellulose nanofilbrils (CNF) and one or more wetting minerals into the slurry;
- and
- (iii) drying the slurry to form a porous matrix material.
1 more element
A method of separating an analyte from a fluid comprising:
- (i) providing a membrane comprising a porous matrix material;
- and
- (ii) contacting the membrane with a fluid comprising an analyte so that the fluid enters the membrane through capillary action, thereby separating the analyte;
- wherein the porous matrix material is a composite material that comprises wood pulp, CNF, and one or more wetting minerals.
