Hierarchically structured microgels of SPIONs, nanofibers, and alginate for copper ion removal

다국어 초록 (Multilingual Abstract)

Microgels have been developed for various practical applications such as heavy metal removal. However,their internal structures are difficult to control for a specific application. This study, for thefirst time,confirms that a hierarchical structure improves the ability of microgels in heavy metal ion removal.
Superparamagnetic iron oxide nanoparticles (SPIONs) were incorporated into polylactic acid nanofiberswhich were then incorporated into alginate microgels, both of which have metal removal capability. Acombination of electrospinning and spraying was used to prepare the microgels. Thefibers outside themicrogels were selectively dissolved out in a subsequent step. Thefiber density inside the microgelscould be controlled by the electrospinning time. This SPION-loaded nanofiber-entrapped alginatemicrogel showed outstanding Cu2+ ion adsorption compared to ones without SPIONs or nanofibers. Thishierarchical microarchitecture of microgel couldfind various applications in thefields of futureenvironmental applications.
