Abstract

The work aims to research the effect of dibutyl succinate on the water-absorbing and water-holding properties of the composite superabsorbents enriched in the sodium salt of carboxymethyl cellulose. The synthesized composite superabsorbents with a different content of dibutyl succinate were analyzed by FTIR, SEM, XRD, DSC, and rheological measurements; equilibrium swelling ratio values, Qe, in distilled water and in a saline solution were determined; and swelling kinetics, water-holding properties, and regeneration ability were researched. It was found that adding 5% w of dibutyl succinate increases Qe values in distilled water up to 51% compared to blank superabsorbents. The effect of a plasticizer is due to its selective interaction with intramolecular H-bond-forming links, which increases the flexibility of the polymeric network and the availability of sorption sites for water molecules. The non-outwashing of a plasticizer in an aqueous medium was confirmed by HPLC–MS. The presence of dibutyl succinate does not change the water absorption mechanism controlled by chemisorption and pseudo-Fickian diffusion of water molecules but accelerates the equilibrium swelling ratio achievement. Also, there is no significant impact of a plasticizer on the water-holding properties of the synthesized superabsorbents at 80 °C, as well as on their reusability, which retains during several swelling-deswelling cycles. So, dibutyl succinate may be applied as an efficient plasticizer enhancing water sorption properties of the composite superabsorbents based on carboxymethyl cellulose sodium salt.
