In this work, we report a facile way to control crystalline structures of polyketone (PK) films by combining plasma surface treatment with chemical vapor deposition (CVD) technique. The crystalline structure of PKs grown on plasma-treated graphene, and the resulting thermal and mechanical properties were systematically discussed. Every graphene sheet used in this work was produced by CVD method, and the production of PKs having different crystallinity were performed on the O2- and N2-doped graphene sheets. The method of controlling crystalline structure of the PKs suggested in this study is expected to be very effective in realizing the PK with good processability, heat resistance, and mechanical properties.
