•Maghemite/PMMA nano-fibres composites were fabricated using electrospinning.•Defect-free and uniform super-paramagnetic nano-fibres composites were produced.•Morphology and structure of the composites were extensively investigated.•Tensile strength of the composite has improved using maghenmite nano-particles.•The super-paramagnetic nano-fibres composite could be use in magnetic applications. In this study, maghemite/PMMA nano-fibrous composites have been successfully fabricated by using the electrospinning process. PMMA nano-fibres have been selected to be used as the matrix; the PMMA was dissolved in three diverse solvents (Acetone, THF and DMF) in order to obtain fine PMMA nano-fibres. As a result, the PMMA–DMF proved to be the most appropriate polymer solution among the three solvents, with its impressive defect-free surface morphology results. The production of maghemite using Massart’s procedure resulted in nano-particles with an average diameter of 4.98±0.13nm (using transmission electron microscopy (TEM)). Maghemite nano-particle were then mixed with a prepared polymer solution in order to fabricate maghemite/PMMA nano-fibrous composite. Furthermore, the investigation of the morphology and structure of the composite was carried out using field emission scanning electron microscopy (FESEM), Energy-dispersion X-ray spectroscopy (EDX), Alternating Gradient Magnetometer (AGM), Fourier transform infrared spectrometer (FTIR), X-ray diffraction (XRD) and tensile strength measurement devices. The results indicated that there was a great amount of maghemite, both in and on the composite’s surface, which can be utilized in the purpose of magnetic applications.
