Usage Instructions

5.1 Usage Guidelines

Because of the strong van der Waals forces and π-π interactions, graphene sheets easily attract each other, leading to agglomeration. To improve the dispersion of graphene, both physical and chemical methods can be employed. Physical methods, such as ultrasonic treatment, utilize high-frequency vibrations generated by ultrasound to overcome the attractive forces between graphene sheets to a certain extent, allowing them to disperse. Chemical methods primarily involve surface modification of graphene, for example, using surfactants. These surfactant molecules can adsorb onto the graphene surface, generating steric hindrance and electrostatic repulsion to prevent the graphene sheets from reagglomerating. It is recommended to use a dispersant during application, with the surfactant (dispersant) addition ranging from 1-5% of the total solution's mass. If unsure about the system type, consult the sales engineer.

5.2 Precautions

5.2.1Graphene dust particles are small and easily inhaled into the human body. Therefore, in work environments with graphene dust, a good ventilation system should be used to reduce the concentration of graphene dust in the air.

5.2.2Graphene exhibits excellent thermal conductivity at high temperatures, so it is important to avoid direct contact with its hot surface to prevent burns.
