Overview
Graphene functional flake is a cutting-edge material that integrates graphene into a flake-like form, offering exceptional thermal and electrical conductivity. It is widely used in industries requiring high-performance materials, such as textiles for smart clothing, electronics for heat management, and composites for enhanced durability. The material's unique properties stem from graphene's two-dimensional structure, which provides superior strength and conductivity. Graphene functional flakes are typically produced through chemical vapor deposition (CVD) or exfoliation methods, ensuring high purity and performance.
Physical and Chemical Properties
Graphene functional flakes exhibit remarkable physical properties, including high thermal conductivity (up to 5000 W/mK) and electrical conductivity. These flakes are also lightweight, with a density ranging from 1 to 2 g/cm³, depending on the composite materials used. Chemically, graphene functional flakes are stable and inert under normal conditions. They are insoluble in water and most organic solvents, making them suitable for various industrial applications. However, they may degrade at extremely high temperatures or under prolonged exposure to harsh chemicals.
Main Applications
Graphene functional flakes are extensively used in textiles to create smart fabrics with enhanced thermal regulation and conductivity. These fabrics are ideal for sportswear, medical garments, and military apparel. In electronics, the flakes are incorporated into heat dissipation systems, such as thermal interface materials and heat sinks, to improve device performance and longevity. Additionally, they are used in composite materials to enhance mechanical strength and conductivity in aerospace and automotive industries.
Safety and Storage
While graphene functional flakes are generally non-toxic, they can cause respiratory irritation if inhaled as dust. Proper handling, including the use of personal protective equipment (PPE) like masks and gloves, is recommended. Storage should be in a cool, dry environment to prevent moisture absorption and degradation. Avoid exposure to direct sunlight or extreme temperatures to maintain the material's integrity and performance.
B2B Procurement Guide
When procuring graphene functional flakes, it is essential to verify the graphene content and purity, typically specified by the supplier. Certifications such as ISO 9001 or material safety data sheets (MSDS) should be requested to ensure quality and safety standards. Price varies based on graphene concentration and supplier reputation. Bulk purchases may offer cost savings, but consistency in batch quality should be confirmed. Reliable suppliers often provide samples for testing before large-scale orders.
