Abstract:
Nanostructures in the form of tubes, wires, crystals, rods, spheres, and fibres have been fabricating and assembling into various macrostructures for a variety of high technology applications. Polymeric nanofiber matrices can be fabricated using a multiply of techniques such as drawing, template synthesis, molecular self-assembly and electrospinning. The last technique provides opportunities to manipulate and control surface area, fiber, diameter, porosity and pore size of nanofibre matrices.Biopolymer/inorganic nanoparticle composites have been the focus of extensive research efforts through the past decade. As such, current research in electrospun nanofibrous composites has focused one of their promising potential on various biomedical areas. Most important applications based on biopolymer/inorganic nanoparticle composites are focused on enzyme immobilization, delivery devices for therapeutic agents, prosthetic/implant devices, bacterial adsorption, dirigible scaffold for in vivo target tissue engineering, and biosensors.In this work we report the obtaining method of PAN/PMMA fibres with magnetic mineral nanoparticles insertion by electrospining. The resulted nanocomposite materials have been characterized using infrared and Raman spectroscopy, scanning electron microscopy and vibration sample magnetometry. The results show that magnetite nanoparticles are well distributed throughout the composite. From the magnetic measurements we can observe a strong magnetization of the nanocomposite samples making them potential candidates for specific biomedical application.
