Highly-efficient and recyclable oil absorbing performance of functionalized graphene aerogel

Three-Dimensional Graphene Interconnected Structure, Fabrication Methods and Applications: Review

“…For example, the graphene hydrogel sample with hydrothermal treatment time of 12 hours had a compressive elastic modulus of 290 ± 20 kPa. This is in stark contrast to the self-assembled graphene hydrogel sample with hydrothermal treatment time of 1 hour that had compressive elastic modulus of 29 ± 3 kPa [37].…”

“…Hong et al [37] investigated the template assisted growth of 3D graphene using porous Al 2 O 3 ceramic. The AAO template is known to be regular and is composed of a 1D channel tray, pore size of approximately 95 nm.…”

“…, [37] implying that the material has a highly thermally conductive reservoir that holds phase change materials for thermal storage.…”

Flexible and Cellulose-based Organic Electronics

“…[29,[135][136] However, non-polymeric materials such as carbon and silica are also often used. [31] In the literature, aerogels have been used in a wide range of applications such as: biomedical application, such as for drug delivery and tissue regeneration [31] , water cleaning and oil absorption [137][138] , thermal insulation [30,[139][140] and supercapacitors [32,[141][142][143] . …”

High structure stability and outstanding adsorption performance of graphene oxide aerogel supported by polyvinyl alcohol for waste water treatment

“…Consequently, the 3D structure is completely destroyed and GO layers disperse into the solvents. Moreover, Fe 3 O 4 /graphene [41], reduced GO [40], rGO/Poly(-acrylic acid) [29], Poly(vinyl alcohol)/Cellulose nanofibrils/GO [33], GO/layered double hydroxides [23] and graphene/Cellulose [42] aerogels are less stable in water, and Graphene/polystyrene/Fe 3 O 4 [43], functionalized-rGO [44] and nitrogen-doped graphene [45] aerogels are stable in organic solvents with no detailing researches about their stabilities in water carried out. Therefore, it can be concluded that, compared to the reported works, the highest stability in different solvents endows the obtained PVA-supported GO aerogel with the highest application value in the field of waste water treatment.…”
