This review considers the most recent developments in supramolecular and supraparticle structures obtained from natural, renewable biopolymers as well their disassembly reassembly into engineered materials. We introduce main interactions that control bottom-up synthesis top-down design at different length scales, highlighting promise of natural associated building blocks. The latter have become actors surge scientific patent literature related to subject. Such make prominent use multicomponent hierarchical polymeric assemblies contain polysaccharides (cellulose, chitin, others), polyphenols (lignins, tannins), proteins (soy, whey, silk, other proteins). offer a comprehensive discussion about exist native architectures (including composite forms), chemical modification deconstruction high axial aspect nanofibers nanorods. reflect on availability suitability types blocks enable superstructures colloidal associations.

The cellulose industry depends heavily on water owing to the hydrophilic nature of fibrils and its potential for sustainable innovative production methods. emergence nanocellulose, with excellent properties, incorporation nanomaterials have garnered significant attention. At nanoscale level, nanocellulose offers a higher exposure hydroxyl groups, making it more intimate than micro- macroscale fibers. Gaining deeper understanding interaction between holds reduce costs provide valuable insights into designing functional nanocellulose-based materials. In this review, molecules interacting are classified free (FW) bound (BW), based their forces surface hydroxyls mobility in different states. addition, water-holding capacity cellulosic materials various detection methods also discussed. review examines water-utilization water-removal fabrication, dispersion, transport aiming elucidate challenges tradeoffs these processes while minimizing energy time costs. Furthermore, influence including mechanical ion conductivity, biodegradability, Finally, we our perspective opportunities developing interplay water.

Abstract Cellulose nanofibrils (CNFs) are supramolecular assemblies of cellulose chains that provide outstanding mechanical support and structural functions for cellulosic organisms. However, traditional chemical pretreatments defibrillation natural produce irreversible surface functionalization adverse effects morphology the CNFs, respectively, which limit utilization CNFs in nanoassembly functionalization. Herein, this work presents a facile energetically efficient engineering strategy to completely exfoliate elementary fibrils from various bioresources, provides with ultrahigh aspect ratios (≈1400) reversible surface. During mild process swelling esterification, crystallinity retained, resulting high yields (98%) low energy consumption (12.4 kJ g −1 ). In particular, on CNF surface, hydroxyl groups restored by removal carboxyl moieties via saponification, offers significant opportunity reconstitution stronger hydrogen bonding interfaces. Therefore, resultant can be used as sustainable building blocks construction multidimensional advanced materials, e.g., 1D filaments, 2D films, 3D aerogels. The proposed new platform fully utilizing characteristics development high‐performance materials.

Abstract Lignocellulosic materials with hydrophobic properties are of great interest for developing sustainable products that can be used in various applications such as packaging, water-repellent and self-cleaning materials, oil water separation or reinforcements biocomposite materials. The hydroxyl functional groups present cellulose provide the possibility to perform chemical modifications cellulosic substrates increase their hydrophobicity. This review is second part a comprehensive on hydrophobization lignocellulosic summarizes recent advances modification substrates. methods described this changes hydrophilicity range from small decrease initial substrate (contact angles below 90°) superhydrophobic above 150°). Additional attention has been paid whether limited surface if it occurs bulk material. We also discuss hydrophobized material packing oil/water purification. Graphical abstract

Natural wood has been used for construction, fuel, and furniture thousands of years because its versatility, renewability, aesthetic appeal. However, new opportunities are arising as researchers have developed ways to tune the material's optical, thermal, mechanical, ionic transport properties by chemically physically modifying wood's naturally porous structure chemical composition. Such modifications can be produce sustainable, functional materials various emerging applications such automobiles, energy storage, environmental remediation. In this review, we highlight recent advancements in engineered sustainable technologies, including thermal light management, remediation, nanofluidics, batteries, structural with high strength-to-weight ratios. Additionally, current challenges, opportunities, future research discussed, providing a guideline further development next-generation, wood-based materials.

Concepts of sustainability must be developed to overcome the increasing environmental hazards caused by fossil resources. Cellulose derivatives with excellent properties are promising biobased alternatives for petroleum-derived materials. However, a one-pot route achieve cellulose dissolution and derivatization is very challenging, requiring harsh conditions, high energy consumption, complex solubilizing. Herein, we design tailoring hydronium ion driven dissociation-chemical cross-linking strategy superfast orderly robust films. In this strategy, there powerful driving force from organic acid pKa below 3.75 dissociate H+ trigger under addition H2SO4. Nevertheless, can only partial swelling but without when above 4.26 dissociation inhibited inorganic acid. The film has transmittance (up ∼90%), tensile strength (∼122 MPa), superior commercial PE film. Moreover, increased 400% compared prepared ZnCl2 solvent. This work provides an efficient solvent, which great significance emerging materials renewable
