Abstract
In this work, an atomic force microscope (AFM) has been used to probe the mechanical properties of polymer samples through examination of force curves produced during tip-sample contact and indentation. Three types of cantilever probes with spring constants estimated to be 0.5-0.6 N/m, 2-3 N/m and 40-60 N/m, respectively, were used to study different polymer samples with known modulus values ranging from 0.5 MPa to 3 GPa. A methodology is developed that (1) relates the elastic modulus of the sample to the sample response measured using AFM force curves; and (2) illuminates the importance of the relative stiffnesses of the cantilever probe and the sample to the determination of elastic modulus.
