Assessing the local nanomechanical properties of self-assembled block copolymer thin films by peak force tapping

The mechanical properties of several types of block copolymer thin films have been investigated using PeakForce quantitative nanomechanical mapping. The samples consisted of polystyrene/poly(methylmethacrylate) with thickness below 50 nm and features of less than 22 nm.
