Product Description

Product Description:
graphene nanoplatelets (by physical method)
The graphene nanoplatelets produced starting from natural flake graphite with physical stripping process to get graphene slurry, then with vacuum freeze-dried process to get the powder,with the advantages of high purity, large specific surface area and high stability.The graphene nanoplatelets stripped by physical method have no oxidation process of strong oxidants, no lattice defects introduced, with excellent electrical conductivity.

Product advantages：
1.with high quality,no lattice defects introduce
2.Low impurity content: fully control of metal impurity content to meet customers' high purity requirement;
3.Good electrical conductivity: graphene nanoplatelets prepared by physical method has fewer defects, with excellent electrical and thermal conductivity
4.Using vacuum freeze-drying,the powder has good redispersibility

Frequently Asked Questions
Q: What types of graphene materials are there?
A: According to the different preparation processes, graphene materials can be divided into two categories: graphene oxide and graphene, and graphene can be divided into graphene nanoplatelets prepared by physical method, usually denoted by GNP, and reduced graphene oxide prepared by chemical reduction process, usually denoted by rGO, according to the different preparation processes.

Q: What are the different conditions of use for these three types of graphene products?
A: GO has better hydrophilicity and can be stably dispersed in water without adding any additives, but some lattice defects are introduced in the process of oxidative intercalation, so GO is almost non-conductive; GNP has a complete lattice and better electrical conductivity, but GNP is highly hydrophobic and extremely difficult to be dispersed without dispersing additives and the number of layers is higher than that of graphene oxide.The conductivity and dispersibility of rGO is between GO and GNP, and it is necessary to add appropriate amount of dispersing additives in the process of using.

Q:How to disperse the graphene powder?
A:Through simple ultrasonic treatment, the graphene powder can be dispersed in agents such as water, ethanol, acetic acid, DMF, NMP, etc

Q:How to do if graphene powder dispersion effect is not so good?
A:A small amount of sodium cholate surfactant can be added to the dispersion system to reduce the surface tension of graphene and enhance its dispersion effect

Q:How to store graphene powder?
A: It is recommended to keep it in ventilated, cool and dry environment, and store it separately from strong oxidizers and flammable materials. Long time storage will lead to powder absorb moisture easily, which can be dried in low temperature before use.

Q: What is the particle size of graphene?
A: At present, the particle size of our rGO with chemical reduction process is less than 5μm, the physical method produced graphene nanoplatelet is 7~*2μm , please contact us for customization if you need other size.
