Formation of graphene nanoribbons in solution
Paiva, M. C.; Cunha, Eunice Paula Freitas; Proença, M. Fernanda R. P.; Araújo, Rui Filipe; Costa, Florinda; Fernandes, António J.; Ferro, Marta A.Recently, the formation of graphene by exfoliation of carbon nanotubes (CNT) has shown increasing interest. This process originates graphene nanoribbons (GNR) that are expected to present excellent electrical properties, depending on their width and on their edge shape [1]. Several methods for the unzipping of graphene from CNT were proposed along the past few years [2-6]. These methods often present some limit...
Functionalization of CNTS with maleic anhydride
Araújo, Rui Filipe; Paiva, M. C.; Proença, M. Fernanda R. P.; Silva, C. J. R.The outstanding properties of carbon nanotubes (CNTs) [1] are mainly related with their unique structural features. However, the high π-π staking between the tubes is a major drawback for their manipulation and interaction with other materials. Chemical functionalization has been used as a convenient tool to improve their performance in various applications [2]. The work reports the functionalization of multi-...
