Graphene oxide (GO) is known to promote crystallization kinetics and change the crystalline morphology for semicrystalline polymers. Previous studies reported that the large specific surface area of GO can provide nucleation sites, which enhances the polymer crystallization on GO reducing the nucleation barrier. However, the crystallization kinetics can be more complex such that the crystallization can be enhanced or suppressed depending on the cooling rate or the GO content. In addition, the GO-polymer interactions at the GO interface can play an important role in changing crystallization kinetics. In this regard, the polymer crystallization with GO is investigated considering the cooling rate and GO content focusing on the GO-polymer interaction employing various experimental methods including polarized optical microscopy, differential scanning calorimetry, and small and wide-angle x-ray scatterings. |
