Title: Polymer-grafted particles at the air/water and oil/water interfaces

Interfaces are the places where the specific phenomena can occur occur due to the asymmetrical nature of the interfaces. I have been investigating on the structures of polymer-grafted particle monolayer at soft interfaces, air/water [1-4] and oil/water interfaces[5] to give insight to the polymer chain conformation at the interfaces by introducingsub-micron spherical particles as a maker. I systematically investigated the effects of molecular weight, graft density, core particle, polymer species, and interface a on the polymethacrylate-grafted particle monolayer structure by π-A isotherm measurement, SEM observation and X-ray reflectivity measurement. The occupied areasobtained in π-A isotherms indicates much larger size than those in the solution and suggests that the grafted polymethacrylates chains are fairly extended on a water surfaces. The tendency is commonly observed in three kinds of polymer species. Molecular weight of grafted polymer, not the graft density, and core particle surface characteristics, is the most effective parameter on the particle monolayer structure, which is contributed by the extended polymer chain conformation.
