“…During combustion, phosphorus generates a polymeric form of phosphoric acid as a char layer, which acts as a shield protecting the material from oxygen (van der Veen and de Boer 2012). Thus, cellulose phosphates have potential to be used as flame-retardant materials (Aoki and Nishio 2010;Cullis et al 1992;Ghanadpour et al 2015;Pan et al 2014). Ghanadpour et al (2015) prepared thermal stable and flame-retardant nanopaper sheets using phosphorylated NFC (Fig.…”

As the most abundant biopolymer in nature, cellulose has become a fascinating building block for the design of functional nanomaterials. Owing to the presence of numerous hydroxyl groups, cellulose provides a unique platform for the preparation of new materials via versatile chemical modifications. This critical review aims to present the advances about nanomaterials based on cellulose derivatives with the focus on cellulose esters within the last two decades, including the chemistry and application of these nanostructured materials. This review starts with the introduction on first fundamental aspects about diverse esterification techniques used up to now to modify cellulose. The in situ esterification for the isolation of nanocelluloses and diverse post esterification methods of nanocelluloses for the surface functionalization were highlighted in the following description. Various esterification strategies and further nanostructure constructions have been developed aiming to confer specific properties to cellulose esters, extending therefore their feasibility for highly sophisticated applications, which were summarized with respect to the categories of the introduced ester moieties. Thus, this review assembles and emphasizes the state-of-art knowledge of functional nanomaterials derived from diverse esterified cellulose compounds.

“…[18][19][20][21] On the other hand, more research interest is evoked towards the use of sustainable materials, such as polysaccharides. [22][23][24][25][26] Polysaccharides as biopolymers have several advantageous features, such as abundance, renewability, nontoxicity, biocompatibility and biodegradability. 14,27 Among them, cellulose is the most abundant natural polysaccharide, which consists of β-(1 → 4)-linked anhydroglucose units (AGUs).…”

Stimuli-responsive nanoparticles from ionic cellulose derivatives

Stimuli-responsive nanoparticles (NPs) based on sustainable polymeric feedstock still need more exploration in comparison with NPs based on synthetic polymers. In this report, stimuli-responsive NPs from novel ionic cellulose derivatives were prepared via a facile nanoprecipitation. Cellulose 10-undecenoyl ester (CUE) with a degree of substitution (DS) of 3 was synthesized by esterification of cellulose with 10-undecenoyl chloride. Then, CUE was modified by photo-induced thiol-ene reactions, in order to obtain organo-soluble ionic cellulose derivatives with DSs of ∼3, namely cellulose 11-((3-carboxyl)ethylthio)undecanoate (CUE-MPA), cellulose 11-((2-aminoethyl)thio)undecanoate (CUE-CA), cellulose 11-(2-(2-(diethylamino)ethyl)thio)undecanoate (CUE-DEAET) and cellulose 11-(2-(2-(dimethylamino)ethyl)thio)undecanoate (CUE-DMAET). CUE-MPA could be transformed into NPs with average diameters in the range of 80-330 nm, but these NPs did not show particular stimuli-responsive properties. Moreover, the dropping technique resulted in smaller NPs than a dialysis technique. Stable NPs with average diameters in the range of 90-180 nm showing pH-responsive and switchable sizes were obtained from CUE-DEAET and CUE-DMAET possessing tertiary amines using nanoprecipitation. Thus, altering the terminal functional groups will be a new approach to prepare stimuli-responsive cellulose-derived polymeric NPs.

“…Similar with that of the decomposition under nitrogen atmosphere, the initial decomposition temperatures of coated cotton fabrics are lower than that of pure one. This reduction is due to the catalytic dehydration and crosslinkage of cotton fabrics by phosphoric acid which is produced during the decomposition of phytic acid in the coating . When the temperature rises to 320 °C, the char residues of coated samples are much higher than that of pure one.…”

Sulfonated melamine-formaldehyde (SMF) resin was successfully synthesized with a mixture of formaldehyde, melamine, and NaHSO 3 in an aqueous solution. Then the SMF was used as the blowing agent to combine with chitosan and phytic acid for fabricating the intumescent flame retardant coating on the surface of the cotton fabric by layer-by-layer (LbL) self-assembled technology. As characterized by X-ray photoelectron spectroscopy, scanning electron microscopy, and attenuated total reflection Fourier transform infrared spectroscopy, the (chitosan/SMF 1 phytic acid) n coating was successfully deposited on the surfaces of cotton fibers. Thermogravimetric analysis results exhibited that the thermal stabilities of coated cotton fabrics under nitrogen and air atmosphere were enhanced at temperatures ranging from 400 to 700 8C compared with pure cotton fabric. At 700 8C, the char residues of cotton-5BL and cotton-10BL under a nitrogen atmosphere were improved 25.9 and 32 wt % than that of pure cotton fabric, respectively. In the vertical flame test, the self-extinguishing could be obtained for the cotton-10BL sample. This work first utilized SMF as negative polyelectrolyte to fabricate intumescent flame retardant coating by LbL self-assembled technology on cotton fabric to strengthen its thermal stability and flame resistance.
