Research on the electromagnetic property of the single-layer graphene-coated fabrics

The single-layer graphene-coated fabrics was prepared using polyurethane as the matrix, graphene as the functional particle and the coating technology on the nylon. The influence of the content and coating thickness of graphene on the the electromagnetic property of single-layer graphene-coated fabrics were studied using the method of controlling variates. The result showed that when the graphene content was 20%, the real and imaginary parts of dielectric constant, the loss tangent, and the shielding effectiveness of the single-layer graphene-coated fabrics were all the largest. The coating thickness was 1.5 mm, the real part of the dielectric constant of the single-layer graphene-coated fabrics was the largest; when the coating thickness was 2 mm, the imaginary part and the shielding effectiveness of the dielectric constant of the single-layer graphene-coated fabrics was the largest; when the coating thickness was 1 mm, the loss tangent of the single-layer graphene-coated fabrics was the largest.

Automated summary

The study showed that a graphene content of 20% and a coating thickness of 1.5mm resulted in the single-layer graphene-coated fabrics with the highest real and imaginary parts of dielectric constant, loss tangent, and shielding effectiveness. Different coating thicknesses had varying effects on the electromagnetic properties of the fabrics, with 2mm coating thickness leading to the highest shielding effectiveness and imaginary part of the dielectric constant, and 1mm coating thickness resulting in the highest loss tangent.
