Nanocomposite materials have a huge potential in future technologies but the creation of optimized nanocomposites with controlled engineering of interfaces has been a challenge. We have worked on different approaches in creating nanocomposites (e.g. carbon nanotube polymer nanocomposites) with good performance and multifunctional attributes. Future of this field will rely on our ability to create complex multifunctional structures with new capabilities such as self-strengthening, self-cleaning, embedded power etc. We are particularly interested in understanding the interphase between matrix and fillers and development of characterization methods to understand the atomic scale structure of the interfaces. We are also interested in optimizing the mechanical (strength, toughness), electrical and optical properties of nanocomposites. In addition to bulk nanocomposites, we are also interested in developing complex, composite (hybrid) nanoscale building blocks.
