Nano-reinforced polymeric systems have demonstrated a great deal of interest
within academia and industry, due to the intrinsic properties of the graphene nanofillers,
having excellent mechanical, thermal and electrical properties. The reinforcement of multiwall
carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) were introduced
into a low cost, non-carcinogenic, high temperature PMR type polyimide resin. The effects
of the interfacial interaction and dispersion quality resulted in improvement in the glass
transition temperature (Tg), elastic modulus and thermal stability by, 31°C, 63% and 16°C,
respectively. In fine, this study presents a simple but effective high temperature polyimide
(HTPI) nanocomposites manufacturing procedure and established that nanoparticle
reinforcement can be used to improve both thermal and mechanical properties.
