The main objective of the present work was to study the role of carbon nanotube (CNT) on the microstructure development and physical, mechanical, and rheological properties of poly(lactic acid) (PLA)/natural rubber (NR)/CNT hybrid nanocomposites. The PLA/NR blend samples with constant blend ratio (90/10) were prepared by melt mixing in a laboratory internal mixer at a temperature of 190°C. The behavior of the PLA/NR blend was examined depending on the CNT content (0.5–6 wt%). The droplet size and droplet size distribution of the NR phase decreases with the increase in CNTs content. This could be explained in terms of compatibilizing effect of CNT and the changing of the viscosity ratio of the blend phases. The development of the microstructure and the physical properties of the blend were also investigated according to the CNT contents by measuring the linear viscoelasticity. The elongational behavior and mechanical properties of the blends were strongly dependent on the location of the CNT. The CNT worked as an efficient compatibilizer and also it worked as a reinforcing filler making the matrix more rigid.

Plasticization Effect

In this paper, the blended materials of poly(lactic acid) (PLA) and thermal plastic starch (TPS) under the plasticization of polyethylene glycol (PEG) 200 were prepared. By detecting the thermal, rheological and tensile properties, it evaluated the plasticization effect of PEG 200 on blended materials. Specifically, for thermal properties, the addition of PEG 200 could improve mobile ability of PLA macromolecules, and accelerated them to form crystalline. But if the content of PEG 200 was more than 10%, this effect was impaired. For rheological properties, PEG 200 could change the fusant of blended materials from pseudoplastic fluid to newton fluid. However, if the PEG 200 was added too much, the blended material was too like perfect newton fluid to be prepared suitably. For tensile properties, when content of PEG 200 was more than 10%, the elongation and tensile modulus would changed sharply. All in all, 10% was the suitable addition parameter for PEG 200. Above this content, the plasticization effect of PEG 200 was too strong to impaired materials properties.
