Abstract

The nanomechanical properties of poly(lactic acid) (PLA)/polycarbonate (PC) blends compatibilized with the compatibilizer and the nucleation agent have been investigated for the first time by Peakforce QNM AFM mode to analyze their structure and mechanical properties. The changes in micro and nano structures and the nanomechanical properties of PLA/PC with the ethylene-maleic anhydride-glycidyl methacrylate terpolymer (EMG) as compatibilizer and talc as nucleation agent were probed. The results showed that the effect of EMG and talc on the modulus and adhesion of the polymers was different, and the reason of the decrease or increase of the modulus of the blends was analyzed. The Peakforce QNM AFM mode was proved to be a powerful tool to investigate the nanoscale behavior of the blends and understand the mechanism of the interaction of the components in the blends.
