Abstract

The ability to achieve enhanced mechanical properties through in-plane orientation of platelet-like nanofillers is a challenge for nanocomposite fabrication and performance. Here we use forced assembly to orient graphene nanoplatelets in PMMAIPMMA-graphene films produced through multilayer coextrusion. Electron microscopy confirms the alternating layer structure of PMMA and PMMA containing oriented graphene. Relative reinforcement of 11 % at a concentration of 0.2 wt % graphene in the total fiLm was achieved without loss of toughness. The reinforcement is attributed to the planar orientation and improved dispersion of the graphene as the layer thickness decreases.
