Influence of the Thickness of Graphene Coating on the Electromagnetical and Mechanical Properties of Double-Layer Coated Basalt Fibre Fabrics

A double-layer coated basalt fibre fabric was prepared using polyurethane as the matrix and applying coating technology to the basalt fibre fabric. The influence of the thickness of the graphene coating on the electromagnetic properties and mechanical properties of the double-layer coated basalt fibre fabric was studied. Results showed that when the thickness of the graphene coating was 2.0 mm, the polarising ability, loss ability and attenuating ability of the fabric with respect to electromagnetic waves were all the largest. Along with the increasing thicknesses of the graphene coating, the electromagnetic shielding effectiveness of the double-layer coated basalt fibre fabric also increased, then the shielding ability against electromagnetic waves became stronger.
