Summary: This review discusses the current knowledge about the formation of layer-by-layer (LbL) self-assemblies using combinations of nanocelluloses (NCs) and polyelectrolytes. It focuses on the fundamentals behind LbL formation with a special emphasis on NCs, as well as the limiting factors for the formation of LbLs of only NCs and the combination of NCs and polyelectrolytes/nanoparticles. The review also highlights the ability of NCs and polyelectrolytes to form dense films with excellent mechanical properties and tailored optical properties, and explores the potential uses of LbLs containing NCs.

Summary: Nanocellulose, a sustainable nanomaterial, has attracted increasing attention due to its versatile applications. This study investigated the viscoelasticity, thixotropy, and yielding behavior of two commonly used nanocelluloses, rod-shaped cellulose nanocrystals (CNCs) and filamentous cellulose nanofibrils (CNFs), to explore their relationship with the structure. The rheological properties of the two suspensions showed strong dependence on concentration and time. CNF suspensions exhibited stronger thixotropy and higher yield stress compared to CNC suspensions, attributed to the higher aspect ratio and stronger structural skeleton of CNF suspensions.

Summary: This study proposes a strategy to regulate the surface properties, charges, and stiffness of CNC composite membranes by incorporating zwitterion and chitin nanofibrils components. The synthesized zwitterion gives the modified CNCs a pH-sensitive charged surface, displaying a cationic form in acidic conditions and converting to an anionic surface in alkaline states. The ionic bridge between the semi-flexible nanofibrils and rigid CNCs effectively reduces the nanohardness of the composite membranes, resulting in uniform surface and microstructural morphologies.

Summary: To overcome the challenges associated with drying and redispersion of cellulose nanofibrils (CNFs), we successfully prepared dried and redispersible CNF powders without the use of additives or conventional drying technologies. The surface properties, morphology, and thermal stabilities were maintained for different surface functionalities, and the rheological properties of the CNFs remained unaffected after drying and redispersion.

Summary: The need for more sustainable printed electronics has led to the exploration of nanocellulose (NC) as a potential material for functional inks and transparent flexible films. NC's unique properties, such as high surface area and reactive hydroxyl groups, make it a versatile additive in ink formulations. Additionally, NC's mechanical, physical, and thermal properties make it an excellent alternative to plastic films. In this study, water-based conductive inks were developed using NC as a template for silver nanoparticles (Ag NPs) and as an additive for ink formulation. The new inks exhibited conductivity levels similar to commercially available conductive inks, and were successfully used to fabricate NFC antennas on NC-coated paper.

This article presents a field-oriented methodology for designing printable local mixtures for various printers. The flowability, pumpability, extrudability, and buildability of these materials are characterized through tests, and two indices (flowability and green strength) are proposed for the classification and control of printability. The results demonstrate the importance of adjusting water content and plasticity, and the addition of cellulose microfibres to improve printability.
