About Single And Multi-Layer Graphene Powder:
Graphene is a kind of new material that is composed of carbon atoms connected by SP ² tightly packed into a monolayer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedical and drug delivery, etc., and is considered a revolutionary material in the future.
Single-layer graphene
What is graphene a single layer of? Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres. Single-layer Graphene refers to a two-dimensional carbon material consisting of a layer of carbon atoms that are periodically packed together in a benzene ring structure (i.e., a hexagonal honeycomb structure).
Graphene (few-layer)
What is few layer graphene? Graphene (few-layer) refers to a two-dimensional carbon material composed of 3-10 layers of carbon atoms stacked in a benzene ring structure (i.e. hexagonal honeycomb structure) in different stacking ways (including ABC stacking, ABA stacking, etc.).
Multilayer graphene
Multilayer graphene, also known as multi-layer graphene, refers to a two-dimensional carbon material composed of the benzene ring structure (namely hexagonal honeycomb structure) with a thickness of more than 10 layers and less than 10nm and the carbon atoms stacked periodically and closely in different stacking ways (including ABC stacking, ABA stacking, etc.).
Single-layer graphene has emerged as a high-performance material capable of replacing outdated technologies, benefiting countless industries. Graphene is very light, but it’s very durable, and it’s able to conduct high levels of electricity through very small amounts of material. Applications for graphene include small electrical circuits and sockets, medical devices, and solar cells. Because of its flexibility, many industry leaders have started using graphene to ensure the safety of their various devices without compromising their efficiency. Single-layer graphene has proven to be a very reliable resource that is both economical and energy-efficient.
Single-layer graphene of the ACS material is available in powder or dispersed form. Single-layer graphene powders are produced using a combination of thermal peel reduction and hydrogen reduction. The monolayer graphene dispersions were created using our own mechanical stripping and dispersion methods. Both products do not contain metal ions and can be used as a conductive agent to improve the high rate of charge and discharge capacity of the battery. In addition to batteries, single-layer graphene powders and dispersants are used in supercapacitors, lead-acid batteries, solar cells, semiconductor chips, graphene films, coatings, and many biological materials.Kmpass is a trusted global Single And Multi Layer Graphene Powder supplier.

Graphene layers consist of ultra-thin layers of carbon atoms arranged in a hexagonal honeycomb lattice. Graphene films produced by chemical vapor deposition (CVD) are polycrystalline in nature, with multiple small graphene domains growing and merging into a continuous film. Compared to single-layer graphene, fewer layers have the potential to develop into materials or heterostructures — by inserting different substances into their layered structures.
How is Single And Multi-Layer Graphene Powder Produced?
The common powder production methods of graphene are the mechanical stripping method, REDOX method, SiC epitaxial growth method, and chemical vapor deposition (CVD) method.
Dispersible monolayer graphene was prepared by complete reduction of GO prepared by Hummer method. Commonly used preparation methods can produce denser graphene, which tends to aggregate. The resulting graphene clumps are insoluble in water or other polar solvents and can no longer disperse, making further treatment difficult. Our dispersible graphene avoids this problem and can be re-dispersed in many solvents.
Applications of Single And Multi-Layer Graphene Powder:
With the gradual breakthrough of mass production and large size problems, the industrialized application of graphene is accelerating. Based on the existing research results, the first fields to achieve commercial application may be mobile devices, aerospace, new energy batteries. With a unique combination of novel electronic, optical and mechanical properties, graphene-based nanomaterials have found applications in energy generation and storage. For example, they are used in basic research, transmission photovoltaic devices, transistors and batteries, new energy batteries, sensors and flexible electronic devices, aerospace fields, photodetectors and biomedical applications (such as drug delivery, biological imaging and tissue engineering), etc.
The research and application development of graphene continue to heat up. Graphene and graphene-related materials are widely used in battery electrode materials, semiconductor devices, transparent display screens, sensors, capacitors, transistors and other aspects. Due to the excellent performance and potential application value of graphene materials, a series of important advances have been made in many fields such as chemistry, materials, physics, biology, environment, energy and so on. Researchers are trying different methods in different fields to produce high-quality, large-area graphene materials. And through the continuous optimization and improvement of the preparation process of graphene, the preparation cost of graphene can be reduced so that its excellent material properties can be more widely used, and gradually toward industrialization.
Storage Condition of Graphene Powder:
The damp reunion will affect graphene powder dispersion performance and using effects, therefore, graphene powder should be sealed in vacuum packing and stored in cool and dry room, the graphene powder can not be exposure to air. In addition, the graphene powder should be avoided under stress.
