Avoiding Aggregation During Drying And Rehydration Of Nanocellulose, Evelyn Fairman
Avoiding Aggregation During Drying And Rehydration Of Nanocellulose, Evelyn Fairman
Honors College
Nanocellulose has attracted attention from academic researchers and industrial corporations worldwide. It is a sustainable raw material with remarkable strength and rheological properties. The industrial production of nanocellulose is an aqueous process; however, many of its valuableproperties are lost upon water removal. Indeed, once dried, nanocellulose irreversibly assembles into a plastic-like material. Currently it can betoo expensive to transport the aqueous suspensions. In order to mitigate high transportation costs, a methodmust be developed to dry and rehydrate nanocellulose whilst maintaining its nano-morphology. The current work demonstrates that the introduction of a cationic surfactant into the aqueous nanocellulose suspensionyields a chemical …
