Abstract

Driven by the search for renewable raw materials and environmental concerns, biomass sub-products have been drawing attention in technology, scientific and socio-economic communities. As a consequence, nanocellulose based materials rise as a potential and essential strategy to an economical (green) sustainable transition. The present proposal intents to develop and to perform a complete study of highly porous materials made up of cellulose nanofibrils (CNF) extracted from sugarcane bagasse. CNF three-dimensional (3D) templates with controlled structure, morphology and porosity will be produced. Morphological and physical-chemistry properties will be simultaneously analyzed through mechanical compression assay and fluids immersion. This innovative approach combines time-resolved in situ X-ray 3D tomography and synchrotron beamline at Sirius in straightforward 4D analysis. The aforementioned simultaneous evaluation will provide a comprehensive feedback of porous materials properties, and their consequent multi-functionalities. Challenges in this proposition will be evaluated: (1) in building up CNF 3D porous materials with controlled structure and morphology; (2) in developing analysis cells and protocols for in situ tomography characterization; (3) in the optimization of data treatment of 3D high-resolution time-space images by computational method. Therefore, the data and results obtained will allow a complete and outstanding understanding of the structure/property correlation of CNF-based porous materials. Moreover, these greener biomass-based materials will be applied afterward in the production of multifunctional materials in several applications. (AU)
