Over the past few years, nanocellulose (NC), cellulose in form of nanostructures, has been proved to be one most prominent green materials modern times. NC have gained growing interests owing their attractive and excellent characteristics such as abundance, high aspect ratio, better mechanical properties, renewability, biocompatibility. The abundant hydroxyl functional groups allow a wide range functionalizations via chemical reactions, leading developing various with tunable features. In this review, recent advances preparation, modification emerging application nanocellulose, especially nanocrystals (CNCs), are described discussed based on analysis latest investigations (particularly for reports three years). We start concise background cellulose, its structural organization well nomenclature nanomaterials beginners field. Then, different experimental procedures production nanocelluloses, functionalization approaches were elaborated. Furthermore, number uses nanocomposites, Pickering emulsifiers, wood adhesives, wastewater treatment, new evolving biomedical applications presented. Finally, challenges opportunities NC-based discussed.

Mechanochemistry for Synthesis

Angewandte Chemie International Edition, Год журнала: 2019, Номер 59(3), С. 1018 - 1029

Опубликована: Июль 11, 2019

Abstract Mechanochemical solvent‐free reactions by milling, grinding or other types of mechanical action have emerged as a viable alternative to solution chemistry. Mechanochemistry offers not only possibility eliminate the need for bulk solvent use, and reduce generation waste, but it also unlocks door different reaction environment in which synthetic strategies, molecules previously accessible solution, can be achieved. This Minireview examines potential mechanochemistry chemical materials synthesis, providing cross‐section recent developments using ball milling formation based on covalent coordination bonds.

Cellulose: A Review of Water Interactions, Applications in Composites, and Water Treatment

Chemical Reviews, Год журнала: 2023, Номер 123(5), С. 2016 - 2048

Опубликована: Янв. 9, 2023

Cellulose is known to interact well with water, but insoluble in it. Many polysaccharides such as cellulose are have significant hydrogen bond networks joining the molecular chains, and yet they recalcitrant aqueous solvents. This review charts interaction of water emphasis on formation both natural synthetic fiber composites. Covering studies concerning wood, biosynthesis cell wall, its dispersion suspensions ultimately filtration fiber-based composite materials this explores water–cellulose interactions how can be exploited for The suggestion that amphiphilic critically reviewed, relevance processing. Building this, progress made using various charged modified forms nanocellulose stabilize oil–water emulsions addressed. role chiral nematic liquid crystals, subsequently when dried into films covered. will also address use an aid one area where used effectively prosper human life.

Ecofriendly Flame-Retardant Cotton Fabrics: Preparation, Flame Retardancy, Thermal Degradation Properties, and Mechanism

ACS Sustainable Chemistry & Engineering, Год журнала: 2019, Номер 7(23), С. 19246 - 19256

Опубликована: Окт. 29, 2019

Flame-retardant (FR) cotton fabrics were successfully prepared with the reactive product of (3-piperazinylpropyl)methyldimethoxysilane and phytic acid, denoted as GPA, through a quick dip-coating technology. The structure, surface micromorphologies, thermal degradation properties, flame retardancy, combustion properties samples assessed. GPA was deposited on fabrics, which proved by results Fourier-transform infrared analysis well scanning electron microscopy coupled energy dispersive spectrometry (SEM–EDS). During vertical burning test, FR cotton-3, an increased mass 14.33 wt %, immediately extinguished after removing igniter, while control entirely burned. deposition to create flame-retardant led serious decrease heat release rate total release. promoted retardancy resulted from formed thermally stable residues held back mass/heat transfer. Thermogravimetric (TG–FTIR) indicated that released more nonflammable gases (H2O NH3) less flammable than control. According TG–FTIR, SEM–EDS, X-ray photoelectron spectroscopy, mechanism proposed.
