Abstract
Abstract The poly(3-octyl-thiophene)/BaFe 11.92 (LaNd) 0.04 O 19 -titanium dioxide/multiwalled carbon nanotubes (P(3OT)/BF–TD/MCNTs) nanocomposites were synthesized through in situ chemical polymerization of 3-octyl-thiophene in the presence of the BF–TD nanocomposites and MCNTs. Nanocomposites were characterized by thermogravimetry (TG), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM). TG, FT-IR and XRD images indicated the formation of P(3OT)/BF–TD/MCNTs nanocomposites. SEM and TEM observations showed the particles size of the BF–TD nanocomposites was less than 50 nm and lots of MCNTs were absorbed by BF–TD nanocomposites. Under applied magnetic field, the nanocomposites exhibited the ferromagnetic behavior. The saturation magnetization, remanent magnetization and coercivity of nanocomposites varied with the content of Ba(LaNd) 0.09 Fe 11.82 O 19 particles. A scheme for the formation of the nanocomposites was proposed. When the BF and TD mass ratio was 6:5, P(3OT)/BF–TD/MCNTs nanocomposites possessed the best magnetic parameter.
