Polymeric nanohybrids containing SiO 2 and C 70 for initiation of aniline polymerization in the presence of CdSe quantum dots

This study presents the synthesis of complex hybrid materials containing SiO 2, polymer and fullerene C 70. The surface of SiO 2 -Br particles was used for the grafting of poly(methyl methacrylate) (PMMA) through ARGET polymerization technique, followed by the grafting of fullerene C 70. The GPC analysis showed that even if the molecular weight increases, the hydrodynamic volume determines lower values with higher PD values. Aniline (ANI) polymerization initiation was achieved by the addition of a C 70 suspension to the ANI – CdSe quantum dots mixture. The polymerization involves an electron transfer process that takes advantage on the difference between the HOMO-LUMO energy levels of the participating species.
