Nanolithographic determination of brittleness at polymer surfaces
AFM techniques were used to interrogate the mechanical properties of weathered polyester copolymer sheets near the exposed surface. Tapping mode tips, as well as a diamond tip mounted on a high spring constant cantilever, were used to scratch overlapping quadrilateral patterns into the polymer. The marred sites were micrographed and the RMS roughness was used as an index of brittleness. Propagation speed and normal force of the test cycle were optimized.
