Graphene Based Wideband Electromagnetic Absorbing Textiles at Microwave Bands

The design and realization of graphene based wideband electromagnetic (EM) absorbing textiles are becoming primary interest. Hence, the development new conductive coatings to be cast onto commercial is crucial. In this article, we propose that conjugate outstanding EM properties at radiofrequency with low-weight, flexibility, cost-effectiveness, washability. With purpose, an innovative production process polyvinylidene fluoride (PVDF) filled nanoplatelets (GNPs) developed for radar-absorbing coated textiles, which fully characterized in terms morphological, electrical, properties. particular, complex dielectric permittivity including different amounts GNPs assessed through measurement a benchmark sample, consequent estimation average GNP size prediction by simulations effective loaded amounts. Such predicted data crucial radar minimum bandwidths −10 dB 5 GHz reflection coefficients below −5 over all frequency range from 8 up 18 GHz. These then produced coefficient free space against plane wave normal incidence. obtained results demonstrate full satisfaction requirements. fact, samples show bandwidth 77% resonant frequency.
