“…This lightly crosslinked three-dimensional structure displays a high capacity to swell by water absorption (Fig. 1); SAPs can absorb as much water as about 10-1000 g/g [12,20]. Although SAPs are mainly used in personal disposable hygiene products they also have several other applications, such as in agriculture, pharmaceutics, separation technology, fibers/textiles, water-swelling rubbers, soft actuators/valves, electrical and construction CMSS-2017 [20].…”

“…Highly crosslinked SAPs made of less hydrophilic monomers have lower absorption capacities. On the other hand, polymers with lower anion density may store the absorbed liquid for longer and, eventually, provide very moderate release of solution [20,23].…”

Towards more sustainable construction–application of superabsorbent polymers in cementitious matrices with reduced carbon footprint

Abstract. Construction industry is constantly searching for sustainable innovations to mitigate negative environmental impacts. Ground granulated blast-furnace slag (GGBS) is a well-known supplementary cementitious material which contributes to reduction of energy and CO 2 emissions from cement industry. However, its use in cementitious systems leads to materials with high cracking susceptibility due to their greater autogenous shrinkage triggered by self-desiccation processes. This problem is even more pronounced when concrete is exposed to severe dry-hot weather conditions, such as in North Africa. In order to mitigate this negative effect of cracking, internal curing agents in the form of Superabsorbent polymers (SAP) can be successfully used. This approach leads to more durable cement based materials and in turn more sustainable constructions.

“…Though the highest swelling performance is often observed at the lowest levels of crosslinking (Bin et al 2000;Wach et al 2001Wach et al , 2002Liu et al 2005a;Demitri et al 2008;Han et al 2010;Pourjavadi et al 2010;Kono and Fujita 2012), it is generally observed that higher levels of crosslinking (or other reinforcement) are needed to achieve the needed mechanical resilience and resistance to dissolution of superabsorbent products (Guilherme et al 2005;Myung et al 2008;Tanaka et al 2005;Schexnailder and Schmidt 2009;Zohuriaan-Mehr et al 2010).…”

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 hydrogels have the ability to respond towards changes in its environmental factors such as pH, temperature and ionic strength. Hydrogels that are responsive to specific molecules (eg: glucose and antigens) can be used as biosensors and as controlled-release delivery systems for bioactive agents and agrochemicals [3]. Recently, the modification of natural polymers is a promising method for the preparation of hydrogels.…”

Abstract. Biocompatible hydrogel based on acrylic acid (AA) and pectin was synthesized using gamma irradiation technique. AA was grafted onto pectin backbone that was extracted from dragon fruit under pH 3.5 and extracts and ethanol ratios (ER) 1:0.5. The optimum hydrogel system with high swelling capacity was obtained by varying the dose of radiation and ratio of pectin:AA. FTIR-ATR spectroscopy was used to verify the interaction while thermal properties were analyzed by TGA and DSC. Swelling studies was carried out in aqueous solutions with different pH values as to determine the pH sensitivity. The results show that the hydrogel with a ratio of 2:3 (pectin:AA) and 30 kGy radiation dose has the highest swelling properties at pH of 10.
