With the development of wearable electronics, designing a strain sensor with high sensitivity, stretchability, durability and environmental stability is necessary but remains challenging. Herein, a high-performance conductive elastomer is reported by incorporating hierarchical cellulose nanocrystal/graphene (MCNC-GN) nanocomplexes into polydimethyl...

Transparent wood-based materials (TWMs), made by either bottom-up or top-down strategies, have attracted great attention owing to their transparency, sustainability and multifunctionality. Compared with materials prepared by a traditional bottom-up method, TWMs fabricated via a top-down approach are promising as the natural hierarchical structure o...

Transparent wood (TW) has been developed to combine the optical and functional aspects of wood. Many efforts have been dedicated to adding quantum dots, nanoparticles, or dyes to TW to provide additional functionalities, such as luminescent, electrochromic, thermochromic, and photo-switchable TW. However, the UV shielding performance and its new ap...

Forests have an important role in mitigating greenhouse gasses and global climate warming by storing carbon. Carbon is locked in trees through photosynthesis, which contributes around 50% of the dry mass of wood. Therefore, wood is critical for maximizing the carbon capture and storage of nature. In this mini-review, emerging technologies for the d...

Large amount of oily wastewater discharged from domestic sources and industrial has caused lots of pollution to our surrounding. Thus, searching effective and eco‐friendly ways for separation of stabilized oil/water emulsions is urgent and highly desirable. Among various methods, membrane with special wettability is an ideal choice for the efficien...

Designing highly porous materials is of great importance for liquid separation, water purification, and disinfection, such as spill oil cleaning and recycling, seawater desalting, and oil/water separation. However, a remaining challenge is to produce porous materials with the characteristics of fast absorption, continuous directional transport, and...

Fused deposition molding (FDM) can complete most complex preparation of drug delivery implants to meet the personalized needs of patients. However, the drug activity has strict requirements on processing temperature and preparation method of filaments, the implant also has strict biocompatibility requirements for the materials. In this study, a dru...

Fire retardant treatments that reduce the heat release rate of wood plastic composites (WPCs) have been intensively studied. However, few studies have reported on increasing the ignition time using precise control of nanostructured hybrids coating on WPC surfaces. Here, a nanocoating layer, composes of polyethyleneimine, Na-montmorillonite (MMT) an...

Next-generation electronics (e.g. substrate and conductor) need to be high performance, multi-functional and environmentally friendly. Here we report the creation of a fully wood-based flexible electronics circuit meeting these requirements, where the substrate, a strong, flexible and transparent wood film, is printed with a lignin-derived carbon n...

Transparent wood (TW) structures in research studies were either thin and highly anisotropic or thick and isotropic but weak. Here, transparent plywood (TPW) laminates are investigated as load-bearing biocomposites with tunable mechanical and optical performances. Structure-property relationships are analyzed. The plies of TPW were laminated with c...

Tremendous efforts have been dedicated to developing effective and eco-friendly approaches for separation of oil-water mixtures. Challenges remain in terms of complex processing, high material cost, low efficiency, and scale-up problems. Inspired by the tubular porosity and hierarchical organization of wood, a strong, mesoporous, and hydrophobic th...

Optically transparent wood combines mechanical performance with optical functionalities is an emerging candidate for applications in smart buildings and structural optics and photonics. The present review summarizes transparent wood preparation methods, optical and mechanical performance, and functionalization routes, and discusses potential applic...

Transparent wood is an attractive structural material for energy-saving buildings due to its high optical transmittance, good thermal insulation, and high toughness. However, thick highly transparent wood is challenging to realize. In the current work, highly transparent wood with a transmittance of 92%, close to that of pure PMMA (95%), is demonst...

Eco-friendly materials need "green" fire retardancy treatments, which offers opportunity for new wood nanotechnologies. Balsa wood (Ochroma pyramidale) was delignified to form a hierarchically structured and nanoporous scaffold mainly composed of cellulose nanofibrils. This nanocellulosic wood scaffold was impregnated with colloidal montmorillonite...

Optically transparent wood, combining optical and mechanical performance, is an emerging new material for light transmitting structures in buildings with the aim of reducing energy consumption. One of the main obstacles for transparent wood fabrication is delignification, where around 30 wt% of wood tissue is removed to reduce light absorption and...

Optically transparent wood (TW) with transmittance as high as 85% and haze of 71% was obtained using a delignified nanoporous wood template. The template was prepared by removing the light-absorbing lignin component, creating nanoporosity in the wood cell wall. Transparent wood was prepared by successful impregnation of lumen and the nanoscale cell...

Enzymatic hydrolysis lignin (EHL) from ethanol production was used as an additive to incorporate in the wood flour/high-density polyethylene (HDPE) composite during the melt extrusion, and the incorporating effects on the mechanical and rheological properties of the resulting composites were investigated. The addition of EHL caused an improvement i...

Chemical modification has been recognized as an efficient strategy for dimensionally stabilizing wood and protecting it from environmental damage, such as deterioration due to weathering and fungal decay during the service period. Studies reported in the literature mainly concern the establishment of workable modification techniques, testing method...
