How to make large size graphene sheet?5 answersLarge-size graphene sheets can be prepared using various methods. One method involves injecting hydrogen peroxide into a mixed solution of graphite powder, mixed acid, and potassium permanganate, followed by diluting, centrifuging, and cleaning the solution to obtain graphene oxide. The graphene oxide is then dispersed and reduced to obtain the large-size graphene sheet. Another method involves coating a substrate with a layer of molten carbon-containing polymer, randomly placing graphene blocks on the polymer, and using a laser light source to scan the area until each graphene block forms a connection with the surrounding polymer, resulting in complete graphene. Additionally, a method involves depositing a metallic membrane on a substrate, spin coating an organic precursor membrane on the metallic membrane, and subjecting the precursor membrane to high-temperature treatment to obtain a graphene membrane. Another method includes preparing a graphene oxide suspension liquid, adding anhydrous ethylenediamine solution, performing a reaction at high temperature, and cleaning the solution to obtain the large-diameter graphene sheet. Finally, a shear exfoliation method can be used to produce large graphene oxide sheets with high yield, which can be further reduced to obtain large graphene sheets with improved properties.
What is the process to make graphene?5 answersGraphene can be produced using various methods. One method is mechanical exfoliation, where graphene layers are separated from bulk graphite. Another method is chemical vapor deposition (CVD) synthesis, which involves a reaction between a gaseous hydrocarbon and a solid substrate to promote graphene growth. The modified Hummer's method is another approach, which uses oxidizing and reducing agents to obtain graphene oxide (GO) from graphene flakes, followed by synthesis of graphene as the final product. Another process involves preparing a mixed solution from graphene oxide, a dispersant, a reducer, and a structure reinforcer, and then subjecting it to freezing and heat treatment to obtain graphene. A physical method includes high temperature shaping, delaminating graphite, stripping and dispersing delaminated graphite, preparing slurry, removing functional groups, and vacuum-drying the product. Another method involves forming a graphite/water mixture and introducing it into a cavitation reactor using offset nozzles, resulting in graphene with high carbon content. Additionally, graphene can be produced by subjecting graphite particles to electrodynamic liquefaction in a vacuum, causing them to split into graphene layers during brittle fracture.
What are the different methods for synthesizing graphene?5 answersGraphene can be synthesized using various methods. The top-down methods include mechanical exfoliation, chemical exfoliation, and chemical synthesis reduction. Mechanical exfoliation involves separating graphene layers from bulk graphite and is suitable for small-scale production. Chemical exfoliation uses chemical processes to obtain graphene oxide from graphene flakes. Chemical synthesis reduction involves reducing graphene oxide to obtain graphene. Bottom-up methods include chemical vapor deposition (CVD), pyrolysis, and epitaxial growth synthesis. CVD synthesis promotes graphene growth by reacting a gaseous hydrocarbon with a solid substrate. Pyrolysis and epitaxial growth synthesis are also used for bottom-up graphene synthesis. Other methods mentioned in the abstracts include hydrothermal methods, electrochemical deposition methods, covalent interaction, and non-covalent interaction.
