Nano Graphene Platelets (NGPs) and NGP Nanocomposites: A Review

Bor Zang, September 2010

The nanoscale graphene platelet (NGP) or graphene nano-sheet is an emerging class of nano materials and can be a low-cost alternative to CNTs and carbon nano-fibers (CNFs). Graphene’s applications as a nano filler in a composite material and as a functional ingredient in an energy system (supercapacitor battery and fuel cell) are imminent. However the availability of processable graphene sheets in large quantities is essential to the success in exploiting composite and other applications for graphene. This presentation begins by a review of the current processes for producing NGPs and their composites and is followed by a discussion on the new advances in materials processes and applications related to NGPs and their nanocomposites.

Graphene Nanoplatelet Additives for Multifunctional Composite Materials

Lawrence Drzal, September 2010

With the emphasis on alternative energy vehicles the need for materials that are not only structural but possess other desirable properties such as electrical conductivity thermal conductivity and barrier properties is increasingly important. Nanocomposites are opening up “windows of opportunity” to not only increase structural properties but also the non-structural surface electrical thermal and barrier properties. Graphite (graphene) nanoplatelets are a new cost-effective nanomaterial that can be used as an additive to polymers and composites to impart multifunctionality without the need for developing new or alternative processing and manufacturing methods. Examples in thermoset and thermoplastic systems -- with and without macro reinforcing fibers -- will be used to illustrate the potential of this nanomaterial.

Mesoporous Silicate Particles (MSP) for Improving Performance and Productivity in Various Composite and Polymer Formulations

Mike Brooks, September 2010

This presentation focuses on a new silicate mesoporous nanoparticle technology which will bring significant productivity and performance benefits to both thermoset and thermoplastic moldings by increasing mechanical properties of neat resins imparting greater flame retardance and reducing processing cycle times. The particles’ intrinsic porous structure allows polymer chains to link the particles into a 3D network improving both strength and modulus at very-low particle loadings (typically 5.0 to 7.5 wt %). The technology does not require organic surface modification to achieve dispersion in the polymer matrix nor does it require retrofitting of processing equipment or modification in processing methods.
