The MSOC Nanochemistry Group has focused its research efforts on the functionalization and purification of carbon nanostructures using non-conventional techniques, obtaining results which show how scaling up the modification of carbon nanostructures is possible using green methodologies. Ball milling treatment and microwave irradiation in the absent of solvents have been the main techniques employed for the preparation of multifunctional derivatives that can serve as versatile synthons in materials science and biological applications. Moreover, the incorporation of those nanostructures in three dimensional polymeric structures is being carried out as an innovative means for obtaining new stimuli-responsive materials as intelligent systems, which can be applied in a wide range of fields such as drug delivery or tissue engineering among others.
Ball milling methodologies in dry media have also being used to cut and functionalize carbon nanotubes and recently, for the exfoliation of graphite and the preparation of stable graphene sheets dispersions in many solvents. This protocol represents, today, one of the best ways of producing stable aqueous dispersions of graphene in macroscopic quantities and has permitted the collaboration with different companies interested in graphene production.
The graphene dispersions can be used for a number of applications, including toxicological and environmental studies, and open the door to the preparation of new graphene composites. In fact, the group is also focussing in the development of new stimuli-responsive materials as intellingent systems, which can be applied in a wide range of fields such as drug delivery or tissue engineering among others.
In our research we collaborate with several other groups in Spain andEurope. All these groups carry on research in the fields of carbon nanotechnology:
-Prof. Maurizio Prato. Università degli Studi di Trieste. Italy. Organic functionalization of fullerenes and other carbon nanostructures.
