NANODISPERSE - Dispersion of Functionalized Fullerenes in Polymer Nanocomposites
(EXPL/CTM-POL/0933/2012)

In this project, polymer-fullerene blend systems were studied to understand from a fundamental level their structure-property relationships, using a combination of detailed materials characterization such as Small Angle Neutron Scattering (SANS), Wide Angle X-ray Scattering (WAXS), Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). The immediate motivation for working with fullerenes comes from the field of photovoltaics where fullerene-polymer mixtures play a critical role in the properties of the devices. However, the results of this work have far wider implications in both fundamental understanding of generic polymer-nanoparticle interactions as well as in other technological applications, such as water purification where the fullerene acts as a catalyst for oxygen excitation.
