“…Compared to unmodified lignin, the high degree of freedom and reactivity of the side chain in lignin–based epoxy acrylate (LBEA) would allow the aliphatic and phenolic ‐OH groups to well participate in the formation of hydrogen bonds and dipole‐dipole interactions with cellulose (Figure S1b, Supporting Information). [ 27 ] Figure S1c (Supporting Information) compares the FTIR spectra of acetone–soluble lignin (ASL) and the corresponding LBEA. The disappearance of the broard peak centered at ≈3403 cm −1 and the sharp peak at ≈1088 cm −1 indicated the consumption of hydroxyl groups during the reaction.…”

Graphene with a 3D porous structure is directly laser‐induced on lignocellulosic biopaper under ambient conditions and is further explored for multifunctional biomass‐based flexible electronics. The mechanically strong, flexible, and waterproof biopaper is fabricated by surface‐functionalizing cellulose with lignin‐based epoxy acrylate (LBEA). This composite biopaper shows as high as a threefold increase in tensile strength and excellent waterproofing compared with pure cellulose one. Direct laser writing (DLW) rapidly induces porous graphene from the biopaper in a single step. The porous graphene shows an interconnected carbon network, well‐defined graphene domains, and high electrical conductivity (e.g., ≈3 Ω per square), which can be tuned by lignin precursors and loadings as well as lasing conditions. The biopaper in situ embedded with porous graphene is facilely fabricated into flexible electronics for on‐chip and paper‐based applications. The biopaper‐based electronic devices, including the all‐solid‐state planer supercapacitor, electrochemical and strain biosensors, and Joule heater, show great performances. This study demonstrates the facile, versatile, and low‐cost fabrication of multifunctional graphene‐based electronics from lignocellulose‐based biopaper.

“…In an approach to use CNFs as both macrophotoinitiator and reinforcement simultaneously, Wu et al proposed a novel strategy to graft CNFs with TDI and photoinitiator 2959 (i.e., MCNFI) which was then grafted onto a photosensitive prepolymer urushiol epoxy acrylate oligomer (UEA) to prepare UV-cured MCNFI@UEA coating. 309 MCNFI@UEA composite coatings. At a loading level of 8 wt% of MCNFI, superior mechanical and anti-corrosive properties of the composite coating were attained that can be accredited to multiple factors such as physical barrier, low water absorption, high adhesion, and passivation effect.…”

“…CM-CNF is highly dispersed under a water-based matrix because of the electrostatic repulsion among the negative ions on the cellulose while forming an excellent barrier coating/ film. In another study, Wu et al 67 synthesized urushiol epoxy acrylate by using an in situ ring-opening reaction with epoxy resin and then esterification with methacrylate anhydride (Figure 12c). In the coating, the modification of the cellulose nanofiber (MCNFI) acts as a bridge connecting urushiol epoxy acrylate molecules, resulting in an increase in the cross-linking density and a decrease in the micropores.…”

With the increasing demand for coatings toward improved comprehensive performance and the implementation of sustainable development strategies, nanocellulose (NC), a renewable and easily biodegradable biomaterial, has been identified as a promising and potential functional/reinforcement additive during the preparation of composite coating materials. Based on recent research, this paper reviews NC itself and its emerging application areas of functionality/enhancement in composite coating materials. In this review, NC materials are divided into two categories of pure NC materials and NC-based composite materials to make a more comprehensive induction of these nanometer-scale materials. The main existing forms and typical examples of NC in various dimensions are introduced followed by a generalization of its preparation and modification methods. NC has been widely utilized to render functionality or strengthen the performance of composite coating materials via its illustrious performance and unparalleled reticulate structure. On one hand, this paper discusses the scientific investigation advances on the multifunctional properties of NC or modified NC that endow coatings with hydrophobicity, dispersibility, corrosion resistance, self-healing, and antibacterial properties. On the other hand, the latest research on polyurethane, acrylate, alkyd ester (oil-modified polyester), and epoxy coatings prepared by utilizing NC as an enhancer is presented.
