▎ 摘　　要

Reduced graphene oxide (RGO)/polyaniline (PANI) composite aerogels (GPAs) with uniformly distributed PANT nanosheets were prepared by a facile self-assembly way. The fabricated hybrids present a cross-linked three-dimensional (3D) porous network, and RGO sheets were covered by PANI sheets with controlled content. The unique architecture efficiently reduced agglomeration of RGO and enhanced the conductive loss of the material to incident wave. Specifically, the GPA composite with 50 wt % PANI showed excellent electromagnetic wave absorption capacity; the largest reflection loss (RL) value reached -48 dB with fill loading of only 3%, and the qualified bandwidth (RL
