 The study presents the preparation of cellulose carbon aerogel at reduced graphene oxide aerogels, CCA at Argeo, and their use as an effective electromagnetic interference, EMI, shielding material and lightweight, flexible composites. The CCA at Argeo's slash polydomethylsiloxane, PDMS, composites have a skin core structure that allows for the construction of a complete three-dimensional double layer conductive network. These composites exhibit excellent EMI shielding effectiveness of 51 dB, which is 3.9 times higher than that of co-blended CCA slash Argeo's slash PDMS composites with the same loading of fillers. The CCA at Argeo's slash PDMS composites also have good thermal stability and conductivity, making them a promising material for lightweight, flexible EMI shielding applications.
