A facile route to synthesis of magnetic phosphazene-containing polymer nanotubes at room temperature

Abstract

Magnetic phosphazene-containing polymer nanotubes were successfully prepared via a facile approach at room temperature by ultrasonic irradiation. The structure and morphology were characterized by XRD, EDX, SEM and TEM. The characterization results show that the phosphazene-containing polymer nanotubes are 50–80 nm in outer diameter and 5–10 nm in inner diameter; the Fe3O4nanoparticles loaded on the outer surface are 5–10 nm in diameter. The coordination behaviour between magnetic nanoparticles and PZS nanotubes was investigated by IR. TG curves show that the magnetic nanotubes have good thermostable properties and high magnetism content. The magnetic properties of the Fe3O4/polymer nanotubes were also investigated. The results show that the magnetic nanotubes have high magnetization saturation value and exhibit good superparamagnetic properties.
