AbstractThe elastic moduli of a range of polymers were characterized by nanoindentation on an atomic force microscope (AFM), using a recently proposed protocol involving a jump in the sample displacement rate. In this method any viscous behavior of the sample would not react to the rate jump, so that the response of the sample reflects only its elastic behavior. By assuming that the AFM tip is a flat-ended punch, this method involves calibration of only two cantilever tip-specific parameters. Experiments were conducted on PMMA at 353 K using load schedules comprising two such rate jumps in sequence and with different magnitudes. The results indicate that PMMA exhibits a constant elastic modulus at the test temperature, and that the AFM tip used is well described by the flat-ended punch approximation. © 2011 Taylor & Francis.
