Transmission electron microscopy measurements reveal that the nanotubes are selectively located in the PA-6 phase. The selectively filled PA-6/ABS blends show a highly irregular, cocontinuous morphology.

L207S) with PMMA. A cocontinuous morphology was identified using the volume fraction ratio and viscosity ratio of the components and dynamic mechanical analysis (DMA). It was observed that PMMA/PLA L210 and PMMA/PLA L207S have cocontinuous compositions at 48 and 28wt% PLA content, respectively. The cocontinuous composition provided superior mechanical properties such as higher modulus. 

Depending on the blend ratio either a core-shell cylindrical morphology (Figure 22(a,c)) or a coreshell cocontinuous morphology (Figure 22(b,d)) were obtained for both blend systems. The driving...

The cocontinuous morphology of PS/PE, PE/PA, PE/PP polymer blends was investigated by Willemse and co-workers [35]. Based on their work, it was found that the interfacial tension was an important parameter in the model as it determined the extended structure, especially its stability. On the other hand, the interfacial tension was responsible for the determination of the phase dimension. It was also concluded that a lower interfacial tension resulted in a broader range of cocontinuity, however, small regions could be formed with the possibility of full cocontinuity in areas of high interfacial tension [35].
