Eco-friendly cellulose nanofibrils with high surface charge and aspect ratio for nanopaper films with ultrahigh toughness and folding endurance

Abstract

Cellulose nanofibrils (CNFs) are a class of emerging sustainable nanomaterials. Among all the advantages, high surface charge offers high colloidal stability, while higher aspect ratio favors the mechanical properties of...

Weakening fibril–fibril interactions via an on-demand regulation of hemicellulose phase towards the facile disassembly of lignocellulose heterostructure into approaching native-state elementary fibrils

“…Colloidal stable CNFs with high-aspect-ratio geometries are highly desirable and perform critical activities in the mechanical, optical, and thermal behaviors of their self-assembled and biocomposite materials. 14 The top-down strategy combining chemical/enzymatic pretreatment with external mechanical processing is the most suitable procedure for exfoliating CNFs possessing fine and uniform diameters ( i.e. , 3–30 nm) from woody/non-woody cellulosic sources in an energy-efficient manner.…”

Natural polyphenolic antibacterial bio-adhesives for infected wound healing

“…38–40 For example, the commonly used monomer, maleic anhydride (MA) could be prepared using cellulose and lignin for a highly efficient biobased synthesis, which has been used in the preparation of eco-friendly cellulose and other polymer materials. 41,42 In addition, numerous anhydrides have been used in the synthesis of various bio-polymers ( i.e. , block copolymers, polymer vesicles, and polymeric peptides) using ring opening polymerization (ROP) reactions, which could be used for biological applications, including antibacterial therapy, 43 drug delivery, 44 and cell therapy.…”
