产品:High-purity single-layer graphene oxide powder 1g
Detailed
Product description
Graphene exhibits good solubility in non-polar solvents, and is super hydrophobic and super lipophilic.
Characteristics
1. Good chemical stability
Except for strong oxidants, it does not react with any substances.
2. Good electrical and thermal conductivity
The resistivity is as high as 0.02-0.03 micro ohm/meter, which is a good electronic conductor; the thermal conductivity is up to 5300W/MK, which is a good thermal conductor.
3. Good mechanical properties
Graphene is a substance known to humans with high strength. It is harder than diamonds. Its strength is more than 100 times that of steel, up to 6x10^7NM/kg.
4. Large specific surface area
Theoretically, the specific surface area of graphene is as high as 2630 m2/g.

Graphene oxide description
1. Graphene oxide (GRAPHENE OXIDE) referred to as GO
2. GO products contain rich oxygen-containing functional groups, soluble in
water, NMP, DMF, ethylene glycol and other solvents, and have good dispersion
properties in solvents such as ethanol and THFD.
3. GO products are characterized by high purity and good dispersibility,
and can be widely used in the field of catalytic materials as a catalyst
carrier for loading nanoparticles, oxides and the like. It can also be used
in the field of environmentally friendly materials to absorb heavy metals,
dyes and other pollutants. It can also be used in polymer composites,
coatings, buried batteries and supercapacitors.

Product characteristics
1. GO can have good dispersing properties in water, and has certain
dispersing properties in polar solvents. Adding a small amount of water can
improve dispersibility. If the dispersibility is poor in a certain solvent,
the addition of an anionic surfactant or a small amount of an amine can
improve the dispersion properties of GO.
2. GO has a strong hydrophilic property, and the water in GO includes free
water, adsorbed water and interlayer water. After drying, there is still some
inter-layer water remaining in the GO.
3. In the process of preparing GO by chemical methods such as HUMMERS, it
is necessary to wash the oil several times. Even if the supernatant is
neutral, the solution of GO dispersion is still acidic, because the graphene
oxide itself contains a -COOH structure.
