New biobased, ecofriendly nanocomposites were prepared from polycaprolactone (PCL)/soy protein isolate (SPI) blend (80/20 wt/wt) with organically modified clay, by melt compounding. X-ray diffraction and transmission electron microscopy analysis revealed that an intercalated nanocomposite was formed and the silicate layers of the clay were uniformly dispersed at a nanometer scale in matrix polymer. There was great enhancement of both tensile and dynamic mechanical properties in the nanocomposite. A rheological study revealed that the nanocomposite exhibits strong shear-thinning behavior in the melted state, and a percolated network of clay particles was formed in the melted state.
