The development of lightweight and integration for electronics requires flexible films with high thermal conductivity electromagnetic interference (EMI) shielding to overcome heat accumulation radiation pollution. Herein, the hierarchical design assembly strategy was adopted fabricate hierarchically multifunctional polyimide composite films, graphene oxide/expanded graphite (GO/EG) as top thermally conductive EMI layer, Fe
