The work explores preparation of new biocompatible magnetic halloysite nanotubes (MHNTs) reinforced polycaprolactone/gelatine nanofibres. MHNTs were prepared by mixing halloysite nanotubes (HNTs) with microwave-synthesized magnetic iron oxide particles suspension. Electrospun nanofibres comprising 8 wt % poly ϵ-caprolactone (PCL) and 8 wt % gelatine (Gel) have been prepared by using eco-friendly solvent - acetic acid suitable for medical applications. The content of MHNT in PCL/Gel nanofibres was 6.0 and 9.0 wt %. SEM observations revealed that the addition of both, unmodified and magnetic halloysite, significantly affected the polymer mixture spinnability and fibre diameter, however the uniformity and homogeneity of nanofibres were much better in nanofibres with magnetic halloysite. In addition of improved structure, application of MHNTs to PCL/Gel nanofibres resulted in the formation of soft ferromagnetic materials with good response to magnetic field.
