“…Previously [15], we found that the dispersed second phase in our hybrid nanocomposites acted as a rigid filler, where the major mechanism controlling fracture toughness is usually crack pinning. The crack pinning mechanism involves two processes: crack trapping and crack face bridging.…”

“…The nanostructure of layered silicate nanocomposites also plays a key role in fracture toughness and its controlling mechanisms as we have previously explained [15].The micron-sized structure of intercalated tactoids of clay is in fact the most efficient microstructure for toughening of simple nanocomposites, those with only a polymeric matrix and clay without a third component. In the case of unsaturated polyester the effect of combinations of clay and thermoplastics on volume shrinkage has been investigated [18,19] but to our knowledge, there are no studies on the toughness of such ternary systems.…”

“…A literatura reporta o preparo de nanocompósitos de PBS e argila principalmente por meios mecânicos, como a extrusão [12,13] . Por outro lado, a técnica de polimerização in situ, contribui para uma melhor dispersão da carga, pois o polímero é sintetizado em meio a esta [14] , permitindo a obtenção de estruturas esfoliadas, capazes de conferir melhores propriedades ao material [15] .…”
