Microhoneycomb Monoliths Prepared by the Unidirectional Freeze-drying of Cellulose Nanofiber Based Sols: Method and Extensions

This method can help answer key questions about achieving functional MHM materials for applications such as filtration, catalyst supporting, flow type batteries, sensors and bio-scaffolds. The main advantage of this technique is that it utilizes the structure directing function of cellulose nanofibers and can realize constitutional control of the targeted MHMs. This method can help answer key questions about achieving functional MHM materials for applications such as filtration, catalyst supporting, flow type batteries, sensors and bio-scaffolds.

Demonstrating the procedure with myself and Cong Wang, a grad student from our laboratory. To begin preparing the tempo-mediated oxidized cellulose nanofiber sol, first combine 66.7 grams of softwood bleached kraft pulp with 700 microliters of deionized water. Mechanically agitate the mixture for 20 minutes at 300 rpm.
