제목 Preparation of waterborne polyurethane/graphene nanocomposite via in situ polymerization method
초록 Recently it has been reported that complete exfoliation of graphite into graphene single sheet can be achieved if adequate pressure is build up at the gallery between the graphite oxide(GO) sheets during rapid heating by CO2 which is evolved by the decomposition of GO functional groups. This completely exfoliated graphite oxide where the inter-graphene spacings associated with GO and that of graphite are completely excluded after thermal expansion, has an affinity to polar solvents and polymers as well as good conductivity, because CEGO is composed of functionalized single graphene sheets(FGSs) having the polar functional groups that are remained even after thermal treatment. In this work, we prepared a new conductive WPU nanocomposites with FGS as a nanofiller without further surface treatment. Their physical and thermal properties, and morphology were examined.
