Abstract The coated polyester cotton fabrics were prepared by coating method, and on plain polyester cotton blended fabrics, polyurethane was used as adhesive, while graphite, bismuth oxide, graphene and their mixtures were used as functional particles. The influences of types of functional particles on dielectric properties, wave-absorbing properties and shielding properties to electromagnetic waves were explored. The results show that the types of functional particles have a great influence on the electromagnetic properties. Within the range 0.01—3 GHz, the coated polyester cotton fabrics with graphene used as the functional particles have the largest dielectric constant and the best electromagnetic protection performance. Within the range 1.98—3 GHz, the coated polyester cotton fabrics with the mixture of graphite, bismuth oxide and graphene used as the functional particles have great impedance matching, the minimum reflection loss, and the best electromagnetic wave absorption capacity, whose the electromagnetic performance was better than the single functional particles.
