Synthesis of Fe₃O₄@Polyaniline Core/Shell Microspheres with Well-Defined Blackberry-Like Morphology

Abstract

Superparamagnetic Fe 3 O 4 @polyaniline core/shell microspheres with well-defined blackberry-like morphology have been synthesized via a simple in situ surface polymerization method. The thickness of the polyaniline (PANI) shell can be selectively obtained by tuning the reaction time and monomer concentration. The poly(vinylpyrroldine) (PVP) plays an important role in the coating process. The present method can be extendable to fabricate other magnetic/conductive core/shell composites, and these unique core/shell spherical materials could find applications in catalyst supports or biomedical areas.

Preparation of core–shell magnetic ion-imprinted polymer for selective extraction of Pb(II) from environmental samples

“…Over the past few decades, Fe 3 O 4 particles, one of magnetic particles, have attracted worldwide attention because of their unique physical and chemical properties, biocompatibility and remarkable magnetic properties [6][7][8][9]. However, the traditional coating of Fe 3 O 4 particles cannot separate analytes efficiently from the complex biological or environmental samples.…”

An Industry Friendly Approach for the Preparation of Magnetic and Electro-Conductive Polyaniline Composite Particles

“…The presence of these peaks confirms that the prepared PANi is composed of both amine and the imine units. In the IR spectrum of PANi, the absorption band at 1293 cm -1 shows the C-N stretching of secondary aromatic amine [14]. The signal at 1131 cm -1 corresponds to B-NH-B, where B refers to the benzenic type ring [15].…”

Removal of As(III) and As(V) from Water Using Magnetic Core-Shell Nanomaterial Fe3O4@Polyaniline

“…In fact, some work has been carried out for the preparation of Fe 3 O 4 @PANI nanomaterials. For example, Fe 3 O 4 @PANI core shell microspheres with welldefined blackberry-like morphology were synthesized via an in situ surface polymerization method [42]. Deng et al prepared conductive core-shell structured Fe 3 O 4 -polyaniline nanoparticles through an in situ polymerization method [43].…”
