Toward a Reversible Consolidation of Paper Materials Using Cellulose Nanocrystals

Abstract: An innovative consolidation strategy for degraded paper is presented based on the reversible application of cellulose nanocrystals as sustainable fillers to reinforce mechanical properties and resistance to further degradation. The compatibility and efficacy of the proposed consolidation treatment are assessed first on pure cellulose paper, used as a model, by reliable techniques such as field emission scanning electron microscopy, atomic force microscopy, tensile tests, X-ray powder diffraction, and Fourier t… Show more

“…Nanocelluloses are a class of fibril-like nanoparticles, comprising packed cellulose polymer chains with at least one dimension in the nanoscale . In general, nanocelluloses exhibit good strength, stiffness, and easily tunable surface chemistry, making them ideal candidates for the fabrication of structured materials, including aerogels, finding application in areas such as insulating materials, biomedical scaffolds, and adsorbents. Depending on the preparation method employed, nanocelluloses can be divided into cellulose nanofibers (CNFs, long and semiflexible fibers with both highly regular crystalline and less well-ordered domains, typically produced via mechanical fibrillation) and cellulose nanocrystals (CNCs, shorter and more rigid fibers with a high degree of crystallinity, typically produced via acid hydrolysis). , Due to the increased flexibility and high aspect ratio of CNFs, they tend to form physically entangled gel networks at low concentrations, while due to the increased rigidity and crystallinity of CNCs, they are often used as mechanical reinforcing agents in composite materials. , …”
