| Abstract: | SAN/PCL/CB nanocomposites were prepared through melt blending styrene-acrylonitrile copolymer/polycaprolactone(SAN/PCL)blends with carbon black(CB).The effects of CB content on the rheological properties,mechanical properties,electrical properties and morphologies of SAN/PCL/CB nanocomposites were investigated.The results show that the addition of CB can induce the phase separation.With the increasing of CB content,the storage modulus(G′)curves of SAN/PCL/CB nanocomposites show a clear"second plateau"in the low frequency region,exhibiting the obvious gelation phenomenon,and the gel point is 6.5%.Around the gel point,the mechanical and electrical properties of SAN/PCL/CB nanocomposites change significantly,indicating that both the mechanical and electrical properties have some correlation with the rheological behaviors.Morphological analysis shows that the addition of CB can effectively reduce the sizes of the dispersed phase,and the agglomerations of CB can be attributed to the rheological percolation. |
