How to prepare graphene powder?
Answer: There are many methods for preparing graphene powder, including mechanical exfoliation method, chemical vapor deposition (CVD) method, redox method, etc. Each method has its advantages and disadvantages and is suitable for different application scenarios and needs.
Why does graphene powder easily agglomerate?
Answer: Graphene powder is prone to agglomeration during preparation and storage due to its high specific surface area and strong π-π interaction. This affects its performance and application effectiveness and therefore needs to be addressed through appropriate dispersion and stabilization techniques.
How to disperse graphene powder?
Answer: Dispersing graphene powder usually requires the use of suitable dispersants (such as surfactants or polymers) and appropriate dispersion techniques (such as ultrasonic dispersion or mechanical stirring). By optimizing the dispersion conditions, the agglomeration of graphene powder can be effectively prevented and its dispersion stability improved.
Is graphene powder harmful to the human body?
Answer: Graphene powder is relatively safe for the human body under normal circumstances, but due to its tiny particle size, it may cause irritation to the respiratory tract or skin if inhaled or exposed to large amounts. Therefore, when handling and using graphene powder, you need to wear appropriate protective equipment and follow relevant safety operating procedures.
How conductive is graphene powder?
Answer: Graphene powder has excellent electrical conductivity and extremely high electron mobility, which makes it have broad application prospects in fields such as electronic devices and energy storage. By optimizing the preparation process and doping technology, the conductive properties of graphene powder can be further improved.
How much does graphene powder cost?
Answer: The price of graphene powder varies depending on the preparation process, purity, particle size and other factors. Generally speaking, high-quality graphene powder is more expensive, but with the continuous advancement of preparation technology and the expansion of market size, its price is expected to gradually decrease.
