Understanding Nanocellulose-Water Interactions to Engineer Advanced Functional Materials — •Valentina Guccini — Uppsala University, Lägerhyddsvägen 1, Uppsala, Sweden

Water interactions are a central topic in the field of nanocellulose due to their pivotal role in nanocellulose's chemical reactivity, processability and physical properties. Yet, a key challenge that remains is bridging the fundamental understanding of nanocellulose-water interactions with the design and engineering of advanced functional materials. This presentation will address this challenge by summarizing the main characteristics of water-nanocellulose interactions and how these can be leveraged to engineer nanocellulose-based materials, in which water has both a structural and functional role. We will analyze the structure-property relationship in nanocellulose-based hydrogels, films and membranes for biotechnological and fossil-free energy applications (e.g. fuel cells and lithium-ion batteries). This presentation offers a new perspective on using nanocellulose-water interactions as a tool to enhance and tailor material performance and functionalities.
