摘要

研究了石墨烯基吸收纺织品在5G频段电磁吸收的可行性。为此，研究了一种新型的石墨烯纳米片填充聚偏氟乙烯(PVDF)涂层的制备方法。所生产的样品进行了形态表征，并评估了电和电磁特性。特别是，在ku波段测量了有效复介电常数，并通过模拟结果预测了频率高达40 GHz的石墨烯基涂层的电磁特性。最后，测量了40 GHz频率下的雷达吸收特性。

Graphene-Based Electromagnetic Absorbing Textiles for 5G Frequency Bands

The feasibility of graphene based absorbing textiles for electromagnetic absorption at 5G frequency bands is investigated. With this aim, a novel manufacturing method for the production of polyvinylidene fluoride (PVDF) coatings filled with graphene nanoplatelets is investigated. The produced samples are morphologically characterized and the electrical and electromagnetic properties are assessed. In particular, the effective complex dielectric permittivity is measured in the Ku-band and the results are used to predict by simulations electromagnetic properties of the graphene based coatings for frequencies up to 40 GHz. Finally, the radar absorption properties are measured for frequencies up to 40 GHz.
