Transitional composition between two thin-film morphologies of the block copolymer, polystyrene-block-poly(tert-butyl acrylate) (PS-b-PtBuA), was investigated using near-field infrared spectroscopy and atomic force microscopy mechanical measurements.

We present molecular dynamics simulations in which we determine the forces on cubes, rods, discs, and spheres that are included in polymer brushes at different distances from the anchoring surface. We show that one can predict the forces on such part

We present a simple method to control the tribological properties of contacts between polymer brushes and a solid counter surface. We show, using atomic force microscopy (AFM) experiments, that the friction force, upon relative sliding of a poly(N-is

We investigated the dynamics of nanometer thin water films at controlled ambient humidity adsorbed onto two atomically smooth mica sheets upon rapidly bringing the surfaces into contact. Using a surface forces apparatus (SFA) in imaging mode, we foun

It was found recently that two polymer brushes in a tribological contact do not interdigitate when each polymer brush has its own preferred solvent, leading to low friction and low wear rates. Here, we demonstrate, using molecular dynamics simulation

Stimulus-responsive (SR), solvated polymers can switch between an expanded state and a collapsed state via external stimuli. Using molecular dynamics simulations, I show that such SR polymers can be employed to control the frictional response between

Solvated polymer brushes are well known to lubricate high-pressure contacts, because they can sustain a positive normal load while maintaining low friction at the interface. Nevertheless, these systems can be sensitive to wear due to interdigitation

Surfaces covered with end-anchored polymers under good solvent conditions have excellent tribological properties. The friction between such surfaces is commonly attributed to steady-state interdigitation of the opposing polymer brushes. However, this
