文摘

Magnetic nanoparticles were synthesized and embedded into the surface of cotton fibers via surface micro-dissolution method using NaOH/urea aqueous solution as dissolving agent, magnetic nanoparticles as the filler, and H₂SO₄/Na₂SO₄ aqueous solution as the coagulant. The magnetic nanoparticles and cotton fabrics were systematically studied by means of scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, thermal gravity, vibrating sample magnetometry, Fourier transform infrared spectroscopy, and tensile testing. The results indicated that treated cotton fabrics contained about 12 wt% Fe₃O₄ and possessed durable magnetic response. Without using any adhesion agents, this surface micro-dissolution treatment provides a simple and green method to introduce nanoparticles into superficial layers of natural cotton fibers.
