| Palavras-Chave | complex electrical permittivity polymer-derived ceramic radar crosssection reflection loss shielding effectiveness |
| Resumo | Materials prepared via the polymer-derived ceramic route have been increasingly studied for protection against electromagnetic energy to mitigate electromagnetic interference. Both experimental and computational evaluations of electrospun SiCN fibers applied to electromagnetic shielding are not yet reported in the literature. This work aims to evaluate the electromagnetic properties of SiCN electrospun fibers by experiments and computational modelling and simulation. Polysilazane and polyacrylonitrile were used respectively as the ceramic precursor and spinning aid. After electrospinning, the fibers were pyrolyzed at 1000 °C. The samples were named SiCN_0, SiCN_40, and SiCN_70 respectively for 0, 40, and 70 wt.% polyacrylonitrile. The scattering parameters, impedances, and reflection losses were collected under X-band (8.2-12.4 GHz) in a vector network analyzer employing the waveguide propagation setup. The experimental scattering parameters were converted through the Nicolson-Ross-Weir method together with the shielding effectiveness and numerical electromagnetic computational studies. Simulations of scattering parameters were performed, and introductory electromagnetic scattering calculations in free space were computed including the radar cross-section (RCS) study. The relative complex electrical permittivity was approximately 3, 4.5, and 4 (real part) and 0.05, 0.22, and 0.1 (imaginary part) respectively for SiCN_0, SiCN_40, and SiCN_70. The SiCN_40 could experimentally store and lose more electromagnetic energy in the material, exhibiting a minimum reflection coefficient of -1.4 dB at 12.4 GHz. The computational simulation corroborated the better performance of SiCN_40 in reflection loss as well as in other electromagnetic spectral responses. Additionally, correlations between electromagnetic properties extracted from experiments and computational results from the RCS study were observed. The free space electromagnetic scattering of SiCN_40 showed better features when compared to the other samples. Owing to the microstructure and product design, SiCN_40 fibers demonstrated satisfying electromagnetic shielding properties in X-band. The computational experiments showed to be a new modelling and simulation approach to evaluate the electromagnetic properties of electrospun SiCN fibers. Further research will focus on material optimization and computational evaluation. |
