In order to alleviate the threats human health caused by electromagnetic radiation, it is high time focus on research into efficient interference (EMI) shielding material. Stainless steel blended (SSB) fabrics are widely used as EMI products. However, they also present bottleneck issues, including poor wave absorbing performance and difficulty in further improving effectiveness (SE). this work, SE of SSB enhanced an improved layer-by-layer assembly method using graphene nanoparticles. The experimental results show that up 10 dB becomes more stable after treatment with method. addition, stainless steel/polyester/cotton increasing mass fraction nanoparticles number assembled layers. increased 10.4 X- K-bands when 2.5 wt.%, layers reaches five. overall increase about 5 dB. Furthermore, frequency range from 3 18 GHz, effective absorption bandwidth 3.6 minimum reflection loss (RL) –27.5 at 14.8 which corresponds 99.8% waves. study confirms can effectively enhance fabrics, providing a feasible strategy for designing absorption-based
