Study on the stability and viscosity of Fe3O4 nano-particles vegetable insulating oils

Vegetable insulating oils are fire-resistant and environment-friendly liquid dielectrics, so it gets wide attention of scholars both at home and abroad. The paper used pyrolysis method preparation the Fe3O4 nano-particles vegetable insulating oil with narrow particle size distribution and high dispersion. The paper also studied on the influence of nano-particles insulating vegetable oil stability and viscosity, with join or not the different types surfactants (CTAB, SDS, PVP) in the preparation of nanometer particle. The results show that, the Fe3O4 nano-particles vegetable insulating oil has good stability, and the viscosity of Fe3O4 nano-particles insulating oil has significant effect with different types and concentration of surfactant.
