[求助] 高分子材料论文翻译求助

The nanocomposite multilayer film composed of substituted BaFe12O19and TiO2was prepared using sol–gel method. The multilayer film is arranged
according to the frequencies of microwave absorption peaks for each layer film. The composite film with the highest absorption frequency is on the bottom. This
arrangement makes more microwave energy to enter the multilayer film and to be absorbed. The microwave absorption property of composite multilayer film is
excellent. The maximum loss efficiency almost reaches–40 dB. The frequency range with the loss above –10 dB is more than 7 GHz. It is much broader than
those of substituted barium ferrites powders. The composite multilayer film is relatively uniform and even. Most grains belong to nanometer scope. The
compounding with TiO2and the nanometer effect also result in the improvement of microwave absorption property of the multilayer film.

由BaFe12O19和TiO2替代的纳米复合材料高分子多层膜根据溶胶——凝胶方法制备而得。该多层膜根据每一层膜的微波吸收峰的频率排列。具有最高吸收频率的复合膜位于底部。这种排列方式能够使更多的的能量进入多层膜并被其吸收。复合多层膜的微波吸收性能是卓越的。最大损失效率几乎达到40 dB。损失超过–10 dB以上的频率范围多于7GHz。这比铁钡氧化物粉末替代物的范围宽。复合多层膜是相对一致且平整的。大多数颗粒属于纳米范围。与TiO2形成复合物及其纳米效果导致多层膜微波吸收性能的改善。
