“…b, extending discharge time from 300 to 550 s, equilibrium swelling presented a trend of first increase and then decrease. This is ascribed to the fact that shorter discharge time (less than 450 s) leads to produce less numbers of free radicals and form a viscous, water‐soluble, and smaller molecular weight of polymers . More than 450 s, a number of monomer radicals and chain radicals can speed up the crosslinking reaction to cause the network shrinkage.…”

“…Recently, we have synthesized successfully some hydrogel by means of GDEP rather than using chemical initiation. Results indicated that GDEP‐initiated polymerization is an extremely promising approach to the development of superabsorbent hydrogel, which has advantages over the others, such as lower cost in set‐up, mild reaction conditions, and simple steps . This technique is generally termed as a clean and environment friendly source of initiation, which is not requiring any additional chemicals and leaving some unwanted residues.…”

“…Moreover, UV light and radiation formed in GDEP can participate in initiated reactions. In addition, HO· radicals generated by GDEP in aqueous solutions can be linked to the polymer chains , so the superabsorbent hydrogel has better hydrophilicity.…”

This article exploits a new approach for synthesis of acrylic acid/carboxymethyl cellulose (AA/CMC) superabsorbent hydrogel in aqueous solution by a simple one-step using glow-discharge electrolysis plasma, in which N,N 0 -methylenebisacrylamide (MBA) was used as a crosslinking agent. The reaction parameters affecting the equilibrium swelling, that is, discharge voltage, discharge time, mass ratio of AA to CMC, content of crosslinker, and degree of neutralization, were systematically optimized to achieve a superabsorbent hydrogel with a maximum equilibrium swelling. The structure, thermal stability, and morphology of AA/CMC superabsorbent hydrogel were characterized by Fourier transform infrared spectroscopy, X-ray diffraction analysis, thermogravimetric analysis, and scanning electron microscopy. The swelling kinetics in distilled water and swelling behaviors in various pH solutions and salts solutions (NaCl, KCl, MgCl 2 , CaCl 2 , AlCl 3 , and FeCl 3 ) were investigated in detail. The effect of six cationic salt solutions on the equilibrium swelling had the following orderIn addition, the pH-reversibility was preliminarily investigated with alternating pH between 6.5 and 2.0. The results showed that the equilibrium swelling of AA/CMC was achieved in 90 min. The hydrogel was responsive to the pH and salts, and was reversible swelling and deswelling behavior.

“…Owing to their super strong water absorption ability, they have been extensively used in agriculture and forestry, construction, medical [4,5] and public health, and daily life supplies [6][7][8][9]. In fact,~90% of superabsorbent hydrogels are disposable products [10,11], and most of them are synthesized by the graft copolymerization between hydrophilic monomers with double bond such as acrylic acid (AA) and acrylamide (AM).…”

Abstract:In this study, the corn straw after removing the lignin was grafted with 2-acrylamido-2-methylpropanesulfonic acid (AMPS) to prepare sulfonated cellulose. The grafting copolymerization between the sulfonated cellulose and acrylic acid (AA) was performed using potassium persulfate and N,N 1 -methylenebisacrylamide as the initiator and crosslinking agent, respectively, to prepare corn straw-co-AMPS-co-AA hydrogels. The structure and properties of the resulting hydrogels were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, and dynamic rheometry. The effects of initiator, crosslinker, monomer neutralization degree, and temperature on the swelling ratio of the hydrogels were studied. The water retention, salt resistance, and recyclability of the corn straw-co-AMPS-co-AA hydrogels were also investigated. The optimum water absorptivity of the corn straw hydrogels was obtained at a polymerization temperature of 50˝C with 1.2% crosslinker, 1:7 ratio of the pretreated corn straw and AA, 2% initiator, and 50% neutralized AA.
