Exploiting CNF Water Interactions in new Applications
We present two examples of new material innovations using porous and moisture responsive 2D- and 3D structures from nanocelluloses. First, we present how hygroscopic and nanoporous networks from cellulose nanofibrils (CNFs) act as capturing elements for colloidal sized nano- and microplastic particles. These hygroscopic nanocellulose assemblies display unique water transport properties, which can transport micro- and nanoplastics into the structure. Secondly, the same inherent properties allow the fabrication of biocompatible CNF hydrogels used as bio-sourced platforms for sustainable chemicals production. In this application, photosynthetic micro-organisms are bound within hydrogels based on TEMPO-oxidized CNF (TCNF), which improves their light-to-product conversion efficiency and decreases their water and energy consumption when compared to traditional suspension culturing. In both cases, the water interactions of nanocelluloses, usually seen as a drawback, are the core contributors that provide advantages for these systems over traditional solutions.
Learning Outcome:
- Describe how the unique properties of nanocellulose can be utilized in new application areas.
- Give examples of how the water interactions of nanocelluloses are utilized in capturing membranes and bioactive platforms for chemicals production.
