In recent years numerous efforts worldwide are addressing all aspects of the rapid developing field of nanocomposites. However, the most important fillers— carbon nanotube and carbon nanofiber—are expensive. In this study, our efforts are aimed at bridging the gap in cost and properties by providing a systematic study of alternative nano materials — nano graphene plate (NGP) and related composites. We fabricated nano graphene plates through the detailed study of raw materials, chemical treatment methods and nano particle dispersion methods. A series of thermal expansion experiments were conducted to investigate the best condition to expand acid treated graphite and expansion ratio of that graphite. Sonication at different levels of energy and ball milling of multiple time durations were used to compare the dispersion efficiency for NGPs. A Particle Size Distribution Analyzer and Scanning Electron Microscope (SEM) were used to study the microstructure and the morphology of the NGP. NGP related nanocomposites were also produced and investigated. The electrical properties were measured by an in-house designed 4–point electrical resistivity measurement device, clearly showing a lower percolation threshold when NGP is used as reinforcement. Thermal mechanical properties were examined using Dynamic Mechanical Analysis (DMA). Improved storage modulus, Tg and loss modulus were also found with increasing concentration of NGP.
