“…The study of superabsorbent polymers (SAPs) has received a great deal of attention due to their application in many fields, such as agriculture and horticulture [1], sanitary goods [2], drug delivery [3,4], artificial implant [5], waste-water treatment [6], biomedical area [7], and so on. The excellent ability to absorb water and/or heavy-metal ions is related to their three-dimensional crosslinked structure [8][9][10].…”

Crosslinking graft polymerization of poly acrylic/montmorillonite superabsorbent composite in aqueous solution was prepared by using glow-discharge electrolysis plasma, in which acrylic acid and acid-activated montmorillonite were used as starting materials, N,N-methylenebisacrylamide as a crosslinking agent. To optimize the synthetic conditions, seven important parameters of the graft-polymerization were examined in detail, such as the discharge voltage, discharge time, the neutralization of acrylic acid, post polymerization temperature, amounts of crosslinking agent, montmorillonite and acrylic acid used in this study. The structure, thermal stability and morphology of product were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, respectively. The absorbency of poly acrylic/montmorillonite superabsorbent was examined to yield the following results: 1,834 g/g for distilled water, 116 g/g for 0.05 mol/L and 75 g/g for 0.15 mol/L sodium chloride solution. Such excellent character could be important to use in many fields, for example, in agricultural and horticultural applications.

“…The energy of active species produced in solution such as • OH, • H, and HO 2 • can initiate many unusual chemical reactions. For example, Sengupta et al [15] found that the yield of • OH radical was 12 mol for the passage of each mole electron of electricity during glow-discharge electrolysis.…”

“…Several studies have recommended the use of cellulose-based materials in absorbent products in order to achieve suitable biodegradability (Cooke 1990;Lokhande and Gotmare 1999;Fei et al 2000;Dutkiewicz 2002;Lionetto et al 2003Lionetto et al , 2005Chang et al 2008;Demitri et al 2008;Singha and Rana 2011). In particular, various studies have demonstrated biodegradable character of hydrogels that contain a cellulose-derived component (Bin et al 2000;Wach et al 2001Wach et al , 2002Lionetto et al 2003;Sahoo et al 2005;Yoshimura et al 2005Yoshimura et al , 2006Wang et al 2008;Feng et al 2010a;Kono and Fujita 2012;Xie et al 2012).…”

Cellulose and some cellulose derivatives can play vital roles in the enhancement of the performance of absorbent products. Cellulose itself, in the form of cellulosic fibers or nano-fibers, can provide structure, bulk, water-holding capacity, and channeling of fluids over a wide dimensional range. Likewise, cellulose derivatives such as carboxymethylcellulose (CMC) have been widely studied as components in superabsorbent polymer (SAP) formulations. The present review focuses on strategies and mechanisms in which inclusion of cellulose -in its various formscan enhance either the capacity or the rate of aqueous fluid absorption in various potential applications.

“…These properties are attributed to the fact that the hydrogel pores dispersed throughout interconnected networks with diameters of several hundred microns create open channels that can move water into the matrix via capillary action [1]. Due to their excellent capability, superabsorbents have been considerably utilized in a number of areas, such as the production of sanitary goods, wastewater treatment, agriculture, and medicine for drug delivery system [2][3][4]. When applied in agricultural soil, superabsorbents accelerate the absorption of nutrients, prolong the retention of water, and improve the fertilizer retention capacity, which can help the germination of seeds and plant growth [5,6].…”

Synthesis and characterization of starch-g-Poly(acrylic acid)/Organo-Zeolite 4A superabsorbent composites with respect to their water-holding capacities and nutrient-release behavior

Novel superabsorbent composites were prepared using starch, acrylic acid, and organo‐zeolite 4A micropowder via aqueous solution graft copolymerization. The effects of organo‐zeolite 4A content on water absorbency were tested to determine the optimum conditions that ensure a high swelling ability. Under these conditions, the maximum swelling ability in distilled water was determined to be 511 g/g when the amount of organo‐zeolite 4A in the feed was 10 wt%. The prepared samples were characterized with Fourier transform infrared spectroscopy, X‐ray diffraction, and scanning electron microscope (SEM). The SEM characterization of the samples indicated that the superabsorbent composites had more pores and water than zeolite‐free superabsorbents. The swelling capacities in distilled water, various salt solutions, and aqueous urea were studied. The on–off switching behavior and the release of urea from the loaded starch‐g‐poly(acrylic acid)/organo‐zeolite 4A were also determined. The results indicated that the novel composite was responsive to salts and exhibited on–off switching behavior, as evidenced by reversible swelling and de‐swelling. In addition, the slow nutrient release makes this material suitable for many potential applications in the fields of agriculture and horticulture. POLYM.
