제목 Neutron Reflectivity Studies on Structure and Properties of Polymers in Slit-like Confinement of Layered Graphene Oxide Sheets
초록 Polymer dynamics near graphene oxide surface is important for a wide range of technological application of graphene-based organic nanoelectronic device. In this presentation, polymer mobility at the polymer/graphene oxide (GO) interface was investigated from the measurement of diffusion and dewetting dynamics. Neutron Reflectivity (NR) has been used to investigate the diffusion dynamics of confined polymer thin film sandwiched between graphene oxide sheets. We found reduction of polymer mobility near GO surface due to its amphiphilic property. This result was in a good agreement with that of dewetting dynamics of bilayer polymer blend with GO monolayer at the interface. Vertical orientation of diblock copolymer of PS and PMMA (PS-b-PMMA) on GO monolayers can also prove their functionality as “an amphiphilic neutral membrane”.
