【 摘 要 】

tsCellulose aerogels were prepared by hydrogen bonding driven self-assembly, gelation and freeze-drying.The skin-core structure of CCA@rGO aerogels can form a perfect three-dimensional bilayer conductive network.Outstanding EMI SE (51 dB) is achieved with 3.05 wt% CCA@rGO, which is 3.9 times higher than that of the co-blended composites.
