Abstract

Bimodal Atomic Force Microscopy (AFM) is a recently developed dynamic AFM technique. Recent work [1] has shown the existence of different regimes of operation in Bimodal AFM depending on the operating conditions. The current work focuses on the effects of different operating parameters while imaging an impact copolymer blend of polypropylene (PP) and ethylene-propylene (E-P) rubber. The higher mode amplitude and phase contrasts reverse at different points between the PP and rubber regions as the free amplitude of the higher eigenmode is increased. The observed contrast reversal suggests that the cantilever kinetic energy and its free air drive input energy play a role in determining the regimes of operation. Understanding the role of cantilever dynamics in determining these operation regimes will help guide a more rational operation of Bimodal AFM.
