abstract = {Iron/silica core-shell microparticles (IMPs) were functionalized by different functional groups including amine,
glycidoxy, phenyl, and thiocyanate. Many of the IMPs modifications are reported for the first time. The resulting
surface chemistry turned out to affect the properties of magnetic alginate hydrogels fabricated from sodium
alginate and dispersed IMPs. Differences in magnetorheological properties of the obtained magnetic hydrogels
can be at least partially attributed to the interactions between alginate and surface functionalities of IMPs.
Density Functional Theory (DFT) calculations were carried out to get detailed insight into those interactions in
order to link them with the observed macroscopic properties of the obtained hydrogels. For example, amine
groups on the IMPs surface resulted in well-formed hydrogels while the presence of thiocyanate or phenyl groups
– in poorly formed ones. This observation can be used for tuning the properties of various carbohydrate-based
hydrogels.},
