“…In the majority of cases, Na-CMC-based hydrogels are obtained through chemical cross-linking as a result of reaction with bifunctional cross-linking agents (for example: epichlorohydrin (Chang et al 2010), diepoxy (Rodriguez et al 2003;Kono et al 2013), dicarboxylic acid (Gorgieva and Kokol 2011;Akar et al 2012), aldehydes (Patenaude and Hoare 2012) and polyethylene glycol (Kono 2014). Also, the synthesis of multi-component hydrogels based on carboxymethyl cellulose have been reported (Maswal et al 2015).…”

The linear dynamic viscoelastic properties and non-linear transient rheology of sodium carboxymethylcellulose solutions (Na-CMC) in propylene glycol/water mixtures were investigated. Measurements were carried out for the solutions of Na-CMC with three different degrees of substitution (DS), namely 0.62, 0.79, 1.04, and the similar average molecular weight (M w & 250,000 g/mol). The strong synergism between the molecules of Na-CMC with DS of 0.62 and 0.79, and propylene glycol has been observed. The occurrence of the overshoot shear stress and the low loss tangent values indicate the physical cross-linking of the polymer chains. The increase of propylene glycol concentration over 80 wt% and sodium carboxymethylcellulose (DS = 0.7) over 1.6 wt% leads to the formation of a physical cross-link network. The absence of overshoot shear stress and terminal behaviour in SAOS flow of the Na-CMC 1.04 solutions in the PG/water mixture shows that no intermolecular cross-linking of polymer chains occurred in them.

“…Chemical-crosslinking provides CMC gels a more stable three-dimensional network. For example, divinyl sulfone [14], epichlorohydrin [15], aldehydes [16,17], fumaric acid [18] and citric acid [19] have been used as crosslinkers to form CMC and CMC composite gels. Monomers with double bond, such as N-isopropyl acrylamide [20] and partially neutralized acrylic acid/rectorite [21], have been initiated by ammonium persulfate and coupled onto CMC backbones via methylene bisacrylamide (crosslinker).…”

Abstract. Biocompatible and biodegradable carboxymethyl cellulose (CMC) has been modified with 4-hydroxybenzylamine (CMC-Ph) in order to prepare CMC-based microgels through the horseradish peroxidise/hydrogen peroxide enzymatic reaction. CMC-Ph was identified as a blend, and the amount of the grafted 4-hydroxybenzylamine per 100 units of CMC was between 17 and 23 according to the molecular weight of CMC. Through a special designed co-flowing microfluidic device, CMC-Ph microgels were prepared with the radius from 100 to 500 µm via adjusting the flow rates of the disperse phase and the continuous phase, respectively. The chondrocytic cell line ATDC5 was encapsulated in the CMC-Ph microgels. The cell-laden microgels were cultured for up to 40 days, illustrating the biocompatibility of CMC-Ph and the microfluidic approach through the enzymatic crosslinking reaction primarily. CMC-Ph showed a great promise to encapsulate the cells for further fabrication of the injectable scaffolds.

“…In this way, particles with a diameter of 81.2 nm were obtained [90]. Other microgels used for textile modi cation have been based on carboxymethylcellulose (CMC) in combination with fumaric acid as a crosslinker [91], di-phenylalanine [83], CMC and hydroxyethyl cellulose [92] and poly (ethylene glycol) (PEG) and poly(ε-caprolactone) (PCL) [61]. In the case of the synthesis of nanogels, PVA- [93], β-cyclodextrin (β-CD)- [94], hydrophobised-pullulan- [95] and collagen-bearing pullulan- [96] based polymers have been used.…”

“…Photo-induced gra copolymerisation of poly-NiPAAm on previously plasma-treated textile substrates has also been carried out through copolymerisation with polypropylene (PP) [99], with the addition of chitosan [100] and with a polyethylene terephthalate (PET) lm [99]. Microgels based on carboxymethyl chitosan (CMCh) and PVA [112], CMC and fumaric acid [91], CMC and hydroxyethyl cellulose derivatives [92], self-assembling di-phenylalanine [83], glycol and ε-caprolactone [62], collagen [30], and polyacrylic acid and β-cyclodextrin [107] have been used. Poly-NIPAAm-based microgels have been by far the most studied because of the LCST of the polymer, which is in the body temperature range.…”

This article reviews hydrogels used for the functionalisation of textile materials. Hydrogels are reviewed according to their reason for incorporation, aspects of crosslinking, stimuli-responsive characteristics and particle size. A more in-depth focus on the eff ect of hydrogel particle size is provided, where macrogels, microgels and nanogels for textile functionalisation are considered. The advantages and disadvantages of each size group are presented. Furthermore, the correlation between synthesis conditions and the sizes of hydrogel particles is discussed, in addition to the applications of macro-, micro-and nanogels to textile materials and their intended uses.
