An elaborate surface-crosslinking method was introduced to enhance the low absorbency under load (AUL) and liquid permeability of itaconic-acid-based superabsorbent polymer (SAP). The effects reaction parameters absorption properties SAP were investigated. increase in content distilled water 1,4-butanediol used as solution improved AUL SAP, whereas an resulted a sharp decrease centrifuge retent...

AIM To develop sustained release matrix tablets based on xanthan as highly water-soluble, cost-effective, non-toxic, easily available, and suitable hydrophilic systems. MATERIAL AND METHODS Xanthan and lignin epoxy-modified resin (LER) mixture were crosslinked using epichlorohydrin as crosslinking agent leading to superabsorbent hydrogels with high swelling rate in aqueous mediums. RESULTS ...

Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these problems. At an early age, the absorbed water by the SAPs may be used to mitigate autogenous and plastic shrinkage. The formed macro pores may...

conventional processes of food dewatering, such as thermal, have undesirable and destruction effects on vitamins, aromatic compounds and pigments. in addition, they are accompanied with some technological complications and energy consumption. thus, food concentration processes are directed to non-thermal techniques or methods with reduced heat effects. superabsorbents are highly hydrophilic pol...

Room-temperature ionic liquid (RTIL), which is a liquid salt at or below room temperature, shows peculiar physicochemical properties such as negligible vapor pressure and relatively-high ionic conductivity. In this investigation, we used six types of RTILs as a liquid material in the pretreatment process for scanning electron microscope (SEM) observation of hydrous superabsorbent polymer (SAP) ...

In this work, an innovative cellulose-based superabsorbent polymer (SAP) was experimentally assessed as an environmentally friendly alternative to acrylate-based SAPs, for the optimization of water consumption in agriculture. The cellulose-based SAP was synthesized and tested for its swelling capability in different aqueous media. The effectiveness of the SAP in agricultural applications was th...

For the first time, it is shown that water medium allows dissolved methylmethacrylate monomer to penetrate water-swollen natural nanoporous structure of never-dried cotton fibers (biological cellulose fibers). Unique cellulose copolymer nanocomposites are obtained by green nanotechnology process (solvent is water -ideal green solventand reaction conducted at 25oC). It was found that after only ...

OBJECTIVE To evaluate the capacity of a superabsorbent dressing (DryMax Extra; AbsorbestAB) to manage excessive exudate, thereby protecting peri-wound skin and facilitating wound healing. METHOD Patients with acute and chronic wounds of various aetiology were assessed, and treatment of their wounds with the superabsorbent dressing was evaluated. The starting point for this study was the needs...
