Flexible broadband wave-absorbing metamaterial based on PPy fabric surface structure and preparation method thereof

Abstract

The invention discloses a flexible broadband wave-absorbing metamaterial based on a PPy fabric surface structure and a preparation method thereof, and belongs to the technical field of electromagnetic wave absorbing materials, the wave-absorbing metamaterial comprises a PPy fabric pattern layer, a fabric dielectric layer and a conductive fabric reflecting layer from top to bottom in sequence; the PPy fabric is formed by a polyester non-woven fabric and PPy loaded on the polyester non-woven fabric fiber; the PPy fabric pattern layer is formed by arranging PPy fabric on the medium fabric in a plane periodic structure. The preparation method comprises the step of sequentially bonding the PPy fabric pattern layer, the fabric dielectric layer and the conductive fabric reflecting layer together by using an adhesive to obtain the flexible broadband wave-absorbing metamaterial based on the PPy fabric surface structure. The flexible broadband wave-absorbing metamaterial based on the PPy fabric surface structure has the advantages of being simple in structure, high in feasibility, environmentally friendly, good in softness, small in thickness, adjustable in broadband and the like, and has good application prospects.
