Intermolecular cooperativity and entanglement network in a miscible PLA/PMMA blend in the presence of nanosilica

SEM micrographs of the fractured surfaces of P/P/Si 2 nanocomposites. The specific “crater” structure is highlighted by the red circle (left panel). A schematic diagram illustrating the composition of the “crater” structure in which a preferential adsorption of PLA molecules on the surface of nanosilica aggregates is suggested.286
