Rapid synthesis of magnetic microspheres and the development of new macro–micro hierarchically porous magnetic framework composites

Abstract

Highly porous magnetic microspheres are synthesised through a flame spheroidisation process and surface functionalised. Metal–organic frameworks are then grown on the surfaces to produce novel hierarchically porous magnetic framework composites.

“…6,7 In previous works, Andrea and co-workers reported the rapid synthesis of magnetic microspheres and the development of new macro-micro hierarchically porous magnetic framework composites using a ball mill. 8 Chang and co-workers reported encapsulating magnetic nanoparticles and quantum dots into porous poly(styrene-co-EGDMA-co-MAA) beads using solvent and high-temperature swelling, respectively. 9 However, these strategies may have a few disadvantages, such as low particle size uniformity, low magnetic nanoparticle load, poor repeatability, limited morphologies of the final composite particles, etc.…”

“…Magnetic polymer composites have been widely studied in various potential applications in material science, such as reduction of dyes, immunodiagnostics, biomedicals, and magnetically controllable photonic crystals due to their large surface areas, fast separation, narrow size distribution, and versatility in surface functionality. − In the early research, many methods have been used to synthesize magnetic polymer composites. , In previous works, Andrea and co-workers reported the rapid synthesis of magnetic microspheres and the development of new macro-micro hierarchically porous magnetic framework composites using a ball mill .
