摘要

本文研究了一种将石墨烯/聚合物纳米复合薄膜层合成具有较好电磁干扰屏蔽性能的PET夹层结构的方法。采用红外光谱、x射线衍射、原子力显微镜、扫描电镜和拉曼光谱对复合材料进行了表征。在8-12.5 GHz x波段,对石墨烯填料与聚(3,4-乙烯二氧噻吩)聚苯乙烯磺酸盐基质在不同厚度下的屏蔽效果进行了研究。

Flexible films based on graphene/polymer nanocomposite with improved electromagnetic interference shielding
In this paper a method to obtain a graphene/polymer nanocomposite film laminated into a PET sandwich structure with improved EMI shielding was investigated. The composite was characterized by FTIR spectroscopy, X-ray diffraction, AFM, SEM microscopy and Raman spectroscopy. The EMI shielding effectiveness was evaluated in 8-12.5 GHz X-band frequencies for different ratio between graphene filler and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate matrix at different thickness of nanocomposite.
