Inverse vulcanised sulfur polymer nanoparticles prepared by antisolvent precipitation–demonstrated as mercury ion absorbent in solution, showing high selectivity and capacity, membrane filters.

Adopting environmentally friendly or green technology and incorporating new alternative substrates for a sustainable agricultural industry has garnered the attention of numerous researchers. Although super absorbent hydrogels have exhibited great potential, natural hydrogel-based absorbents gained more interest due to their safe properties. The sources novel polymer are easily obtained from was...

Examining the behaviour of dense suspensions has proven to be difficult, both experimentally and numerically. Using super water–absorbent polymer, PIV measurement was successfully conducted in a hydrogel suspension with volume fraction (VF) Φ =20% (see Zhang Rival, 2018). However, due slightly refractive index mismatch, image quality will degrade significantly as particle loading is increased. ...

In this work, we present a novel ex situ modification of bacterial cellulose (BC) polymer, that significantly improves its ability to absorb water after drying. The method involves single inexpensive and easy-to-perform process BC crosslinking, using citric acid along with catalysts, such as disodium phosphate, sodium bicarbonate, ammonium bicarbonate or their mixtures. particular, the mixture ...

We consider the multidirectional swelling and drying of hydrogels formed from super-absorbent polymers water, focusing on elastic deformation caused by differential swelling. By modelling as instantaneously incompressible, linear-elastic materials considering situations in which there can be large isotropic strains (arising swelling) while deviatoric remain small, it is possible to describe acc...
