2021 TAPPI NANO Webinar Series: Exploiting CNF water interactions in new applications Webinar

Monday, October 25, 2021 to Monday, October 25, 2021

9AM - 10AM (ET)

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:

  1. Describe how the unique properties of nanocellulose can be utilized in new application areas.
  2. Give examples of how the water interactions of nanocelluloses are utilized in capturing membranes and bioactive platforms for chemicals production.
