Graphene Nanoplatelets Design Service

Graphene nanoplatelets (GNPs) are a cutting-edge class of carbon nanomaterials, prized for their exceptional properties. These include ultra-high electrical and thermal conductivity, outstanding mechanical strength, and a vast surface area. At CD Bioparticles, we understand that the full potential of these materials is unlocked when they are precisely tailored to the specific needs of an application. Our graphene nanoplatelets design service offers a comprehensive, end-to-end solution for researchers and industries looking to leverage these unique properties. We partner with you to design and synthesize GNPs that meet your exact specifications, ensuring optimal performance and breakthrough results in your projects.

Unrivaled Technical Expertise

Graphene nanoplatelets are stacks of a few to tens of layers of graphene sheets, with a thickness in the nanometer range. They are distinct from single-layer graphene in that they offer a more cost-effective and scalable alternative while retaining many of the superior properties of graphene. The number of layers, lateral dimensions (width and length), and surface chemistry of GNPs can be precisely controlled, which directly influences their behavior and performance in various applications. This tunability is at the core of our service, allowing us to create materials that are not just "good enough" but are perfectly suited for your specific requirements.

Our Services

Our service allows for the precise customization of a wide range of parameters. This flexibility is what sets us apart and enables us to create truly unique materials.

1. Number of Graphene Layers

The number of graphene layers is a critical factor influencing the properties of the GNPs.

• Few-Layer Graphene (FLG): Typically 2-10 layers. These GNPs exhibit excellent electrical conductivity and are highly sought after for advanced electronics, sensors, and energy storage devices.
• Multi-Layer Graphene (MLG): More than 10 layers. These are ideal for applications where mechanical strength, thermal conductivity, and cost-effectiveness are paramount, such as in polymer composites, conductive inks, and thermal management solutions.
• We can precisely control the synthesis process to target a specific range for the number of layers, providing a material with properties optimized for your application.

2. Lateral Dimensions (Platelet Size)

• The lateral dimensions of the GNPs play a crucial role in their dispersibility, rheological properties in liquids, and their ability to form interconnected networks.
• Small Platelets: Typically <5μm. These are easier to disperse and are often used in applications requiring high surface area and uniform distribution, such as in catalysts and batteries.
• Large Platelets: Ranging from 5−50μm or even larger. These are excellent for creating highly conductive percolation networks in composites and conductive films, leading to lower loading requirements to achieve desired properties.
• We can produce GNPs with a narrow size distribution, or a broad one, depending on your application's specific needs.

3. Surface Functionalization

• The surface chemistry of GNPs is often the most important factor for achieving stable dispersion and strong interaction with the host matrix. Our custom functionalization services allow you to overcome common challenges like agglomeration and poor interfacial bonding.
• Oxygen-Containing Groups: Functionalization with hydroxyl (−OH), carboxyl (−COOH), and epoxy groups enhances dispersibility in polar solvents and allows for chemical bonding with polymer matrices.
• Nitrogen-Containing Groups: Amine (−NH2) and other nitrogen functionalities can be introduced for specific chemical reactions and improved compatibility.
• Polymer Grafting: We can graft specific polymer chains onto the surface of the GNPs to improve their compatibility with a wide range of polymer matrices, a process known as "grafting-to." This creates a truly integrated composite system.
• Other Surface Modifications: We also offer custom functionalizations with a variety of other molecules and groups to meet specialized requirements for biomedical, catalytic, or sensing applications.

4. Purity and Defects

• The purity of GNPs and the presence of defects can significantly impact performance. We provide customization options for purity levels (e.g., carbon content) and can control the defect density to balance cost and performance.

Application of our designed graphene nanosheets

• Composite Materials

Graphene nanosheets designed by CD Bioparticles are widely used in composite materials to improve their mechanical, electrical, and thermal properties. By incorporating our customized GNP into polymers, metals, ceramics, or cement, the strength, stiffness, toughness, conductivity, and thermal conductivity of the resulting composite materials have been improved.

• Electronics and Optoelectronics

Graphene nanosheets with customized electrical properties are an ideal choice in the fields of electronics and optoelectronics. They can be used as conductive fillers in printed electronic products, transparent conductive films, sensors, and transistors.

• Energy Storage and Conversion

In the field of energy storage and conversion, the graphene nanosheets we designed play a crucial role. They are used as electrode materials for lithium-ion batteries, lithium sulfur batteries, and supercapacitors, improving their energy density, power density, and cycle life.
