AM-FM stiffness map of a ternary polymer blend using blueDrive photothermal excitation

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 μm scan.
