The influence of functionalized MWCNT reinforcement on the thermomechanical properties and morphology of epoxy nanocomposites
Source abstract
Abstract
Abstract The nature of the interphase, often considered the third phase of nanocomposites, has been a central topic in nanocomposites research. In this study, an ionic bonding scheme was employed to graft epoxy-compatible amine terminated linear polypropylene oxide (A-PPO) molecules of different molecular weight to oxidized multi-walled carbon nanotubes (o-MWCNTs), and thereby modify the interphase of MWCNT-epoxy nanocomposites. The amine-cured epoxy systems reinforced with different functionalized MWCNTs demonstrated divergent thermomechanical properties. Fractography revealed distinct fracture behaviour for nanocomposites with long-chain A-PPO modified MWCNTs. The results demonstrate the feasibility of interphase control and performance engineering through the judicious choice of polymer grafts.
