AM-FM image of a Ternary Polymer Blend

Three component polymer blend (Polystyrene, Polypropylene, Polyethylene) imaged with AM-FM Viscoelastic mapping mode. Image shows topography with an overlay of sample stiffness. AM-FM imaging was performed using blueDrive? photothermal cantilever excitation on a Cypher S AFM, 15 ?m scan.
