Structure and property gradation from surface to bulk of Poly(l-lactic acid)/Poly(d-lactic acid) blended films as estimated from nanoscratch tests using scanning probe microscopy.

Abstract

Structure and property gradation from surface to bulk of poly(L-lactic acid)/poly(D-lactic acid) (PLLA/PDLA) blended films was estimated from nanoscratch tests using scanning probe microscopy (SPM). The PLLA/PDLA blended film was prepared by melting, following isothermal crystallization at 150 °C due to the formation of stereocomplex crystal (sc-crystal… (More)
