Polyacrylamide‐grafted carboxymethyl cellulose: Smart pH
A novel application, utilizing polyacrylamide‐g‐carboxymethyl cellulose (CMC‐g‐PAM) in concentrating dilute solutions of Bovine serum albumin (BSA), was investigated. The grafting reaction parameters were investigated and the hydrogel smartness was verified.
Carboxymethyl cellulose (CMC), a major cellulose derivative, is a linear anion polymer cellulose ether that is widely applied in many fields including food, textile, paper-making, painting, pharmaceutical and cosmetics industries (Jiang et al., 2016). CMC can be oxidized by periodate to form dialdehyde carboxymethyl cellulose (DCMC) that
Carboxymethyl cellulose/polyacrylamide composite hydrogel
Carboxymethyl cellulose/polyacrylamide composite hydrogel for cascaded treatment/reuse of heavy metal ions in wastewater. A new bio-based CMC/PAM composite hydrogel was prepared as a bioadsorbent. A new bio-based bilateral hydrogel containing carboxymethyl cellulose (CMC) and polyacrylamide (PAM) was prepared for the wastewater remediation.

Cellulose-Based Composite Hydrogels: Preparation
Cellulose hydrogels have high mechanical strength and good permeability for liquids, gases, and electrolytes, the composite hydrogels which combine cellulose and extracellular matrixes are very
A range of cellulose-derived polymers that can form hydrogels exist [24,34] and the cellulose-derived polymer chosen for this study was sodium carboxymethyl cellulose (CMC-Na/CMC) as it was shown to be easily hydrated and exhibited self-healing properties . CMC is a hydrophilic cellulose derivative with carboxymethyl groups bound to the
Carboxymethyl cellulose-g-poly(2-(dimethylamino) ethyl
The surface morphologies of the hydrogel before and after MO adsorption are depicted in Fig. 5. CMC-g-PDMAEMA hydrogel exhibited a macroporous 3D structure with a pore diameter of about 20 μm (Fig. 5A). After the adsorption of MO, the expanded pores completely collapsed (Fig. 5B).
Results of hemolysis assay indicated that the citric acid crosslinked carboxymethyl cellulose-tamarind gum hydrogels were safe to be used in drug delivery. These results indicated that the citric acid crosslinked carboxymethyl cellulose-tamarind gum composite hydrogel films has the potential to be used in topical novel drug delivery systems.

A novel application, utilizing polyacrylamide‐g‐carboxymethyl cellulose (CMC‐g‐PAM) in concentrating dilute solutions of Bovine serum albumin (BSA), was investigated. The grafting reaction parameters were investigated and the hydrogel smartness was verified.
Magnetic/pH-sensitive nanocomposite hydrogel based
Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide (MBA) as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and magnetic montmorillonite ( mMT) nanoclay as nano-filler.
Injectable hydrogels based on carboxymethyl cellulose and dextran, reinforced with rigid rod-like cellulose nanocrystals (CNCs) and aldehyde-functionalized CNCs (CHO–CNCs), were prepared and characterized. The mechanical properties, internal morphology, and swelling of injectable hydrogels with unmodified and modified CNCs at various loadings were examined. In all cases, gelation occurred
