“…Besides their notable intrinsic properties, the functionalities of graphene and CNTs may be enhanced through the mentioned chemical functionalization 98,99 or even by the association with other materials (i.e., composite materials). [100][101][102] A signicant number of papers and reviews have been describing the key points of functionalization methodologies that lead to materials used in the most varied propositions: sensing devices, electronics, drug delivery system, plasmonic, biosensing, improving their wetting or adhesion characteristics and their dispersion stability, among others. [103][104][105][106][107][108] Important works, such as from Poplawska 109 and Kim 105 et al described, respectively, organic reactions along with their mechanisms, and a broad analysis of functionalization routes and the resulting applications of the obtained materials.…”
