Product Description
| Graphene oxide description 1. Graphene oxide (GRAPHENE OXIDE) referred to as GO 2. Graphene oxide 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. Graphene oxide 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. Graphene oxide 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. Graphene oxide 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 Graphene oxide 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. | ||||||||
