▎ 摘 要
Herein review truly became interesting due to all results found in the papers consulted, mainly, because graphene-based materials have gained significant attention of late due to their outstanding physicochemical properties, and, because there are a lot of articles about graphene materials. First, in this review paper, we focus on the advantages and disadvantages of the graphene-based materials synthesis methods (top down and bottom up), and then, the aim was carried out a review of the scientific literature related to the characterization of graphene materials by means of calorimetric techniques from differential scanning calorimetry (DSCs) and with special emphasis on the study of solid surface-molecule interactions that those establish their performance on many interfacial phenomena, by the definition of the reactivity and selectivity by means of the immersion calorimetry, isothermal titration calorimetry and adsorption calorimetry. With DSC and TGA analyses, it was possible to verify that graphene or graphene materials are good fillers, that they disperse well in a polymeric matrix, and that they generate a notable improvement in the mechanical and electrical properties in the nanocomposites obtained. These analyses also showed that graphene or rGO is better dispersed than GO and that GO can be reduced in the synthesis of the nanocomposite. These analyses also demonstrate the compatibility of graphene with metals such as aluminum and GO with silver, resulting in decorated nanocomposites. These analyses also showed that graphene or rGO is better dispersed than GO and that GO can be reduced in the synthesis of the nanocomposite. About the use of calorimetric techniques like immersion, adsorption and isothermal titration provide valuable information on the actual interaction between a molecule and a study surface; for example, the study of interaction of graphene materials with small organic molecules was compared with the classical approach using the Van't Hoff approximation, finding that Delta H-ads(0) evaluated by Van't Hoff approximation has been reported endothermic while the ITC measurements revealed that the adsorption of MB on both unmodified and acid-modified CNTs is an exothermic process.
