Selective Localization of Spherical Silica Particles in Heterophase Poly(lactic acid)/ Low Density Polyethylene Blends

摘要

In this article, different strategies to control the localization of spherical silica particles in Poly(lactic acid)/ Low density polyethylene blends were studied. These strategies include different sequences of addition of components and compatibilization. Results show that using these different strategies, the controlled localization of silica particles in either the matrix or in the dispersed phase can be achieved. Long processing times used in this study show that the observed localization is stable and does not change with further processing.
