One-pot synthesis of size- and morphology-controlled 1-D iron oxide nanochains with manipulated magnetic properties†
Abstract
Polypropylene grafted maleic anhydride (PP-MA, 2500 g mole−1) has demonstrated its unique capability to synthesize 1-D ferromagnetic hard (292.7 Oe) γ-Fe2O3 nanochains made of ∼24 nm nanoparticles vs. PP-MA with 8000 g mole−1 for the synthesis of 1-D ferromagnetic soft (70.5 Oe) γ-Fe2O3 nanochains (30 nm) made of flowerlike nanoparticles.
