“…Besides using nanopapers for two-dimensional reinforcement in composites [25,26], NC in the form of dense fibre networks, e.g. cellulose nanopapers [27], is also an important material for various advanced applications, including filtration membranes [28][29][30], packaging [31] and substrates for flexible, printed electronics [32]. Thereby, the ability to design [33], tailor and engineer the physical properties of nanopapers is of upmost importance.…”

Cellulose nanopapers have gained significant attention in recent years as large-scale reinforcement for high-loading cellulose nanocomposites, substrates for printed electronics and filter nanopapers for water treatment. The mechanical properties of nanopapers are of fundamental importance for all these applications. Cellulose nanopapers can simply be prepared by filtering a suspension of nanocellulose, followed by heat consolidation. It was already demonstrated that the mechanical properties of cellulose nanopapers can be tailored by the fineness of the fibrils used or by modifying nanocellulose fibrils for instance by polymer adsorption, but nanocellulose blends remain underexplored. In this work, we show that the mechanical and physical properties of cellulose nanopapers can be tuned by creating nanopapers from blends of various grades of nanocellulose, i.e. (mechanically refined) bacterial cellulose or cellulose nanofibrils extracted from never-dried bleached softwood pulp by chemical and mechanical pre-treatments. We found that nanopapers made from blends of two or three nanocellulose grades show synergistic effects resulting in improved stiffness, strength, ductility, toughness and physical properties.This article is part of a discussion meeting issue 'New horizons for cellulose nanotechnology'.

“…These headways of green innovation, minimal-effort paper substrates, and solutionbased natural thin film transistors are promising for use in the future for adaptable devices application [275]. In another study, Hassinen et al [276] revealed entirely printed top-gate bo om-contact natural paper transistors by utilizing substrates arranged from CNFs and monetarily accessible printing inks to create the gadgets. Gravure printing was used to coat the substrate with a polymer instead of diminishing the surface harshness and closing the surface.…”

Primary material supply is the heart of engineering and sciences. The depletion of natural resources and an increase in the human population by a billion in 13 to 15 years pose a critical concern regarding the sustainability of these materials; therefore, functionalizing renewable materials, such as nanocellulose, by possibly exploiting their properties for various practical applications, has been undertaken worldwide. Nanocellulose has emerged as a dominant green natural material with attractive and tailorable physicochemical properties, is renewable and sustainable, and shows biocompatibility and tunable surface properties. Nanocellulose is derived from cellulose, the most abundant polymer in nature with the remarkable properties of nanomaterials. This article provides a comprehensive overview of the methods used for nanocellulose preparation, structure–property and structure–property correlations, and the application of nanocellulose and its nanocomposite materials. This article differentiates the classification of nanocellulose, provides a brief account of the production methods that have been developed for isolating nanocellulose, highlights a range of unique properties of nanocellulose that have been extracted from different kinds of experiments and studies, and elaborates on nanocellulose potential applications in various areas. The present review is anticipated to provide the readers with the progress and knowledge related to nanocellulose. Pushing the boundaries of nanocellulose further into cutting-edge applications will be of particular interest in the future, especially as cost-effective commercial sources of nanocellulose continue to emerge.

“…As electronics are moving toward being inexpensive, flexible, lightweight, environmentally friendly, biodegradable, or even biocompatible, the interest in the fabrication of electronics on inexpensive and flexible opaque and hazy cellulose substrates has renewed. [38,114,120,121] With the emergence of advanced electronic materials, for instance, π-conjugated organic molecules and polymers, graphene, carbon nanotubes (CNTs), and silver nanowires (Ag NWs)/nanoparticles, opaque and hazy cellulose substrate is considered a perfect platform for integrating with these functional materials through advanced manufacturing techniques (e.g., supercalendering, [113] inkjet printing, [122][123][124] and 3D printing [117] ) to prepare multifunctional substrate for a wide range of electronic applications.…”

Versatile wood cellulose, the most prototypical abundant polymer on earth, is considered a promising natural material for the fabrication of biodegradable electronics. The development of biodegradable electronics may help alleviate the adverse environmental impact caused by the fast‐growing electronic waste (e‐waste). The focus of this review is to discuss recent major advances in biodegradable electronics with versatile wood cellulose in terms of supporting substrates and functional components. First, the biological biodegradation and structural hierarchy of versatile wood cellulose is briefly introduced, followed by highlighting three types of cellulose substrates (opaque and hazy cellulose paper, transparent and clear cellulose film, and transparent and hazy cellulose film) for biodegradable electronics. Then, recent progress and research achievements in the use of versatile wood cellulose with multiscale dimensions in biodegradable electronics as a functional component (e.g., advanced light management layer, high capacitance dielectric, and ionic conductor) or even smart materials (e.g., mechanochromic layer, humidity sensing layer, adaptable adhesive layer, and piezoelectric component) are summarized in detail. Finally, an overview of challenges and perspectives for biodegradable electronics with versatile cellulose is provided.
