Preparation of amino-functionalized graphene oxide/polyimide composite films with improved mechanical, thermal and hydrophobic properties

- GO functionalized with p-phenylenediamine (PDA) exhibits good dispersibility and compatibility with the polymer matrix.
- Covalent incorporation of GO-NH2 into polyimide via in situ polymerization and thermal imidization.
- Significant reinforcement on the mechanical properties, hydrophobic behavior and thermal stability of the PI/GO-NH2 nanocomposites.
