Ene airgel structure regulation of the urban environment where the graphite progress

Graphene is a two-dimensional honeycomb nanosheets carbon sp2 hybrid constructed embodiment, because of its excellent physical and chemical properties and a large theoretical specific surface area, in the field of optoelectronics, catalysis, sensors, environmental restoration, etc. are showing good application development prospects. The graphene sheet assembly constructed three dimensional network structure Aerogels , not only to maintain the excellent characteristics of good sheets, while environmental remediation applications also facilitate recovery and recycling, an important application of the development of graphene direction. Sol – gel graphene airgel is the most common method of making, but gelled sheet stacking assembly process inevitably face sheet layer may occur, resulting airgel specific surface area, more brittle structure, fragile. Although a large number of studies show that present to modify the structure by introducing a variety suppressed stacking sheets, and the like to enhance the mechanical properties of the airgel, but only by how easy regulation nanosheet layer structure itself can achieve the same purpose it is difficult to achieve. Urban Environment nanoenvironment Institute, Chinese Academy of Functional Materials Group (paid out to study group) based on the existing research graphene-based, nano-regulation by the distribution of the oxygen-containing sheet structure, disrupt hydrogen bonding network of the sheet surface had stabilized, the nano sheet wrinkles can occur in a simple aqueous solution, suppressing self-stacking sheet while the sheet was found using built airgel layer having superior mechanical and elastic hydrophobic. The adsorption capacity of the airgel common organic solvents and oils up to 154-325 g / g, the adsorption capacity with respect to conventional airgel increased 224% -406%, organic pollutants in water can be used in an efficient select removed. The research infrastructure based on nano-sheets, make full use of the advantages of two-dimensional material structure, optimize the performance of aerogels, but also stressed the importance of basic research structure.
