聚邻乙氧基苯胺/Fe3O4复合薄膜的制备及吸波性能
Preparation and Microwave Absorbing Properties of Poly (o-ethoxyaniline)/Fe3O4 Nano-Multilayer Films
摘要
Abstract
Poly(o-ethoxyaniline)/Fe3O4 nano-multilayer films were prepared by layer-by-layer electrostatic self-assembly. Poly(o-ethoxyaniline) was synthesized by chemical oxidation and Fe3O4 fluid was obtained by hydrothermal method. The morphologies, electromagnetic parameters and microwave absorbing properties of the film were characterized by means of scanning electron microscope (SEM) and vector network analyzer. The SEM picture indicated that the film was sheeted. The film had both magnetic loss and dielectric loss, but had magnetic loss predominantly. Besides, in the lower frequency range (8 - 10 GHz) , when the thickness of the film was 3. 5 mm, microwave absorbing effect is better and the minimal reflection loss is -11.5 dB. In the lower frequency range (10-12. 5 GHz) , the minimal reflection loss is -10. 4 dB when the thickness of the film was 2. 5 mm.关键词
