Graphene properties surface area

For more efficient utilization of MOFs sorbents, several hybrid systems based on MOFs with other solid sorbents have been investigated in the literature. The objective of having hybrid materials is to utilize the synergism between the two sorbents and therefore ultimately improve the overall performance in C02 separation. Moreover, sorbents such as activated carbons, graphenes, and CNTs provide the added feature of high surface area and easily functionalized sites which contribute to the tuning of the final properties of the composite... 

Nanocarbon structures such as fullerenes, carbon nanotubes and graphene, are characterized by their weak interphase interaction with host matrices (polymer, ceramic, metals) when fabricating composites [99,100]. In addition to their characteristic high surface area and high chemical inertness, this fact turns these carbon nanostructures into materials that are very difficult to disperse in a given matrix. However, uniform dispersion and improved nanotube/matrix interactions are necessary to increase the mechanical, physical and chemical properties as well as biocompatibility of the composites [101,102]. 

The three-dimensional continuous nanostructured framework has a large specific surface area and favors rapid electron and ion transport in polymer-based electronics. The previously mentioned polymer composites with three kinds of structures can form three-dimensional porous structures when they were stacked. Besides, polymers can be incorporated into porous silica, carbon, and graphene as the retaining frameworks to form three-dimensional structured composites. The resultant composite materials exhibit surface properties of the polymers and high mechanical strength and high electric conductivity of the frameworks, which will provide new possibilities for advanced applications. The structures, such as the cormectivity, pore diameters, and shapes, are mainly decided by the frameworks.

In recent years, carbon nanotubes (CNTs) and graphene have been extensively studied due to their outstanding electron mobility, mechanical strength and large specific surface area [1]. These properties make them attractive in a wide variety of applications ranging from sensors and actuators [2], catalysts [3], batteries...
