Photovoltaic conversion is one of the domains in which Nanocomposites could be currently developed. Conjugated polymer-inorganic nanocomposites have been studied because of favorable electronic and optical properties, in particular polymer/C60 [1, 2] or polymer/TiO2 [3,4,5,6,7]. To reach a good conversion rate, a fine dispersion of inorganic particles in the conducting polymer matrix could be a real asset [8, 9]. Several routes were successfully considered through the sol gel synthesis. However the aggregation of inorganic particles remains the scouring problem of the dispersion , particularly caused by the use of solvents .
In this study, we propose an original way based on the in situ synthesis of dioxide titanium particles in a molten polymer [12 13], where no solvent will be used. A model approach was developed to allow a better understanding of the interaction between organic and inorganic phases.
