Abstract

In the present study, attempts have been made to prepare nanocomposites based on Polylactide (PLA) and acrylonitrile butadiene rubber (NBR) and 4 wt% of organically modified nanoclay (Cloisite 10A) via melt mixing process in an internal batch mixer for the first time. To investigate the effect of acrylonitrile (ACN) content of NBR phase on the dispersion state and localization of silicate nanolayers and micromorphology of blends, three different NBRs with low (19%), medium (33%) and high (51%) ACN content were employed. X-ray diffraction, scanning electron microscopy, and transmission electron microscopy were conducted on the prepared samples. The size of dispersed NBR droplets decreased by the incorporation of nanoclay into the composition of all PLA/NBR blends, irrespective of the ACN content. This is mainly attributed to the reduction of the coalescence of the rubber droplets by the clay platelets. However, the reduction in NBR droplets size by the nanolayers was more pronounced for the nanocomposites having high ACN rubber phase as a result of higher localization of clay platelets within the interface of PLA and NBR. XRD analysis revealed that nanoclay mainly located at the interface of PLA/NBR-H, as the intensity of the peaks was quite similar for the nanocomposites with different rubber content.
