Exceptional Electrical and Thermal Performance

This graphene sheet stands out with remarkably high electrical conductivityup to 10^6 S/mand thermal conductivity approaching 5000 W/mK. These assets deliver advanced energy and heat management capabilities essential for electronics and research applications requiring minimal power loss and efficient thermal dissipation.

Precision Engineered Single-Layer Structure

Crafted using chemical vapor deposition (CVD) or mechanical exfoliation, each monolayer sheet measures just 0.34 nm in thickness. Lateral sizes typically range from 5 to 50 microns, offering impressive consistency, purity (>99%), and structural integrity suitable for industrial and laboratory settings.

Versatile Applications and Reliable Packaging

Graphene sheets are ideal in electronic devices, sensors, batteries, composite materials, and EMI shielding. Packed in sealed anti-static containers, they remain stable for up to two years when stored in cool, dry conditions, making them reliable for manufacturers, researchers, and industrial users.

FAQs of Graphene Sheet:

Q: How is the graphene sheet produced for high purity and uniform thickness?

A: The graphene sheet is produced through chemical vapor deposition (CVD) or mechanical exfoliation, both methods enabling control of the monolayer thickness (0.34 nm) and ensuring purity greater than 99%. These advanced production techniques facilitate consistent lateral sizes and minimal defects.

Q: What are the main benefits of using a monolayer graphene sheet in electronic applications?

A: Monolayer graphene sheets offer high electrical conductivity (up to 10^6 S/m), exceptional thermal management (~5000 W/mK), and a large surface area, making them ideal for developing high-performance electronics, sensors, and energy storage devices with improved efficiency and reduced losses.

Q: Where should graphene sheets be stored to maintain their shelf life?

A: Graphene sheets should be stored in sealed anti-static packaging in a cool, dry environment, away from moisture. This preserves their quality and functionality for up to two years, preventing contamination and degradation.

Q: What is the recommended process for handling and using graphene sheets safely?

A: It is best to handle graphene sheets with clean, dry gloves to prevent the introduction of moisture or contaminants, and to use anti-static tools or surfaces. Despite being non-toxic, following standard laboratory safety and storage protocols prolongs product performance and ensures safety.

Q: When are graphene sheets preferred over other carbon forms in industrial applications?

A: Graphene sheets are chosen for applications requiring ultrathin yet strong materials with exceptional electrical and thermal conductivity, such as electronics, sensors, batteries, and thermal management systems, where conventional forms like graphite may not offer the same performance characteristics.

Q: How does the insolubility of graphene in water affect its potential usage?

A: Graphenes insolubility in water means it cannot be used in aqueous solutions, but it is compatible with certain organic solvents, facilitating its integration in specific composites, coatings, and processing methods for advanced material engineering.
