A highly self-healable and recyclable electromagnetic interference shielding (EMIS) nanocomposite film is prepared, and its various properties are investigated in this study. A water-soluble functional matrix (WFM) is synthesized by reacting different structures of diol (1,6-hexanediol, 1,4-cyclohexcandiol, or Isosorbide) with 2,2-bis(hydroxymethyl) propionic acid, poly(ethylene glycol), and isophorone diisocyanate. A series of EMIS nanocomposite films are fabricated by blending graphene nanoplates (GNPs), carbon nanotubes (CNTs), a conjugated polymeric surfactant (CPS), and WFM. The EMIS film based on a heterocyclic (isosorbide) moiety shows enhanced electrical and mechanical properties and excellent tensile recovery compared to EMIS films based on aliphatic (1,6-hexanediol) and alicyclic (1,4-cyclohexcandiol) moieties. These results are attributed to multiple internal interactions resulting from the complexation of CPS-modified GNPs and CNTs, and the functional heterocyclic matrix.
