Abstract
The combination of a scanning force microscope (SFM) with an integrated microindenter makes it possible to investigate mechanical properties of polymers and their blended systems with high spatial resolution. The behaviour of the polymers polycarbonate (PC), polymethyl methacry- late (PMMA), and PC=PMMA blends were investigated using nanoindentation with different mechanical load, fre- quency, and development of inelastic deformation with time. The results of the microscopic measurements were compared with macroscopic properties from tensile test experiments. The relation of the Young's moduli of the macroscopic and microscopic tests of the neat polymers are comparable.
