 This study developed a novel EMI shielding composite material based on cellulose aerogel at reduced graphene oxide, CA at RGO, and polydomethylsiloxane, PDMS. The CA at RGO was prepared by vacuum impregnation, freeze drying followed by thermal annealing, and then loaded into the PDMS matrix. This resulted in a three-dimensional, 3D, double layer conductive network, which improved the EMI shielding effectiveness, EMI-C, from 13 dB to 51 dB. Additionally, the thermal stability, THRI, and thermal conductivity coefficient, lambda, were also greatly enhanced. These results indicate that the CCA at RGO slash PDMS EMI shielding composites have excellent potential for applications in lightweight, flexible EMI shielding composites.
