The decrease of the glass transition in polystyrene thin films with decreasing film thickness has given rise to the suggestion that there is a region near the free surface where there are faster dynamics than in the bulk. This surface mobility has been directly measured, but there are few studies of how the enhanced dynamics varies with distance from the free surface. We have used...
Thin polymer films are commonly used as samples in numerous areas of materials physics. Techniques applied to the preparation and application of thin films, including etching and nanolithography, often involve the addition of a solvent to the polymer surface. It is currently understood that there exist two classifications of polymer solvents. Good solvents are used to fully dissolve a polymer...
Vibrational sum frequency generation (SFG) spectroscopy is a non-destructive interface-specific non-linear optical spectroscopy that delivers information about the structure and composition of interface environments. Coupling and energy flow through vibrational modes at surfaces are important and of interest in areas ranging from membrane biophysics and biochemistry, to materials science,...
It is well know that even in equilibrium the dynamics of a polymer in solution are affected by hydrodynamics and follow Zimm, rather than Rouse, dynamic scaling. However, due to the difficulties in correctly simulating a polymer in a real solvent, most simulations of polymers in solution have used Langevin dynamics which do not include hydrodynamics. My group has created a package for the...
