Since its recent successful isolation, graphene has attracted an enormous amount of scientific interest due to its exceptional physical properties. Graphene incorporation can improve electrical and mechanical properties of polymers including polyethylene (PE). However, the hydrophobic nature and low polarity of PE have made effective dispersion of nano-fillers difficult without compatibilization....
Polystyrene-b-polylactide (PS-PLA) was employed as a precursor to nanoporous thin films containing perpendicular cylindrical channels. Cylinder-forming PS-PLA was spin coated onto Si substrate and solvent annealed using acetone, chlorobenzene and tetrahydrofuran (THF) for different durations. By atomic force microscopy, three types of final morphology were observed at the free surface of the films...
