  Abstract

Ultrasonic-assisted in situ synthesis was performed using bacterial nanocellulose (BNC) and magnetite nanoparticles (Fe3O4 NPs) to synthesise superparamagnetic membranes as BNC/Fe3O4 nanocomposite films (BNC/Fe3O4 NCFs). Vibrating sample magnetometry of these BNC/Fe3O4 NCFs exhibited superparamagnetic properties with high saturation magnetisation at 40.57 emu g-1. Morphology of BNC/Fe3O4 NCFs was studied by field-emission scanning electron microscopy. Results showed Fe3O4 NPs with diameter 30 to 50 nm trapped in a BNC structure. Fourier transform infrared spectroscopy analysis confirmed the incorporation of BNC and Fe3O4 NPs. Thermal properties of the nanocomposite films increased with Fe3O4 NPs in the BNC structure compared with native BNC. Surface wettability of BNC/Fe3O4 NCFs was determined by contact angle and revealed hydrophobic properties. Results showed that ultrasonic-assisted in situ synthesis of superparamagnetic BNC/Fe3O4 NCFs is an important property when utilising BNC/Fe3O4 NCFs with a hydrophobic nonpolar polymeric matrix in electronic device applications.
