摘要：

Ti-doped barium ferrite nanoparticles was prepared by Sol-Gel method. Barium ferrite was doped by Ti without any change of the lattice structure, but the particle size was changed greatly. BaFe12-xTixO19/PANI nanocomposites was synthesized by in situ polymerization. The FTIR spectra shows that there is an interaction between barium and polyaniline chains. Ti-doping changed the electromagnetic parameters of BaFe12O19/PANI nanocomposites and enhanced it's microwave absorption property. BaFe11.6Ti0.4O19/PANI nanocomposites has the largest microwave absorption of -42.9dB at 14.8 GHz with the thickness of 2mm. When the absorbing coating thickness is in the scope of 2 mm to 4 mm, the reflection loss is below -10 dB in frequency range of 5.5 similar to 17.8 GHz, means the nanocomposites can absorb electromagnetic waves effectively.
