In Situ Polymerization of Barium Hexaferrite Ferrofluids for Poly(Ethylene) Succinate Magnetic Nanoparticle Composites

Journal of Applied Polymer Science, Volume 142, Issue 23, June 15, 2025.
ABSTRACT The integration of hard magnetic barium hexaferrite (BHF) nanoplatelets into a dense poly(ethylene succinate) (PES) polyester matrix produces an exciting biodegradable thermoplastic magnetic polymer nanocomposite. In this work, scandium‐substituted BHF nanoplatelets are grown and stabilized in hexadecyltrimethylammonium bromide (CTAB ...

Triple‐Stimuli Responsive Soft Robots with Photo‐Programmable Ferriferous Oxide Particle Patterns

Advanced Science, Volume 12, Issue 18, May 15, 2025.
The in situ generation of Fe3O4 nanoparticles in polymer substrate is realized by combining photo‐reduction of Fe3+ to Fe2+ and hydrolytic reaction of the two ions. By spatiotemporal control of UV light irradiation, the distribution of Fe3O4 nanoparticle can be well controlled, which enables the composite with magnetic field, NIR light, and moisture ...

Solvothermal Synthesis of SrFe12O19 Hexaferrites: Without Calcinations

Journal of Superconductivity and Novel Magnetism, 2014
In this study, the effect of temperature on the hydrothermal synthesis of single-phase SrFe12O19 hexaferrite (SrM) was investigated. For this synthesis, annealing or calcination process was applied. The Fe/Ba molar ratio was taken as 8:1. In this study, single-phase SrM NPs were synthesized via hydrothermal method.
