Graphene and its derivatives are today one of the latest and hottest research topics. This is due to their exceptional mechanical, electrical, thermal and optical properties, high surface area-to-volume ratio, and unique crystal structure. Therefore, many applications, for instance, electronic devices, composites and nanomedicine, are expected. This research aims to study the mechanical and thermal properties of poly(lactic acid)/graphene oxide (PLA/XGO) nanocomposites. The polymer nanocomposites were successfully prepared by solution processing in conjunction with compression molding at various contents of XGO from 0-1.0 wt%. The structure, mechanical properties and thermal stability of the composite materials have been investigated by the X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), mechanical test, and thermogravimetric analysis. The results obtained from those different studies revealed that PLA and XGO could mix with each other homogeneously. A uniform dispersion of filler in the matrix existed when the XGO content was less than 0.7 wt%. Mechanical properties of biopolymer were greatly improved by the addition of a small amount of XGO (0.5 wt%). The nanocomposites have potential application as packing materials..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
