Large-diameter graphene oxide sheet requires controlled handling to preserve flake size and prevent degradation. Avoid prolonged ultrasonic exposure, maintain dispersion temperature below 40°C, and store in dry, light-protected conditions with a maximum unopened shelf life of 6 months.

Ultrasonic Treatment Limitations: Prolonged ultrasonic exposure reduces sheet diameter and must be avoided.
Dispersion Temperature Control: Dispersion temperature must be maintained below 40°C to prevent material degradation.
Storage Requirements: Store the material dry and protected from light to maintain stability.
Shelf Life: Unopened material should be used within 6 months of receipt.

FAQ

What is the significance of the >5 µm sheet diameter and 1-6 layer structure for graphene oxide research?

The >5 µm sheet diameter and 1-6 layer structure define a large-flake graphene oxide with a broad lateral dimension and thin layer count, which is critical for applications requiring high aspect ratio and accessible oxygen functional groups. These properties support dispersion and chemical modification while maintaining sheet-form handling, as noted in the product overview.

How should large-diameter graphene oxide sheets be handled during dispersion to preserve sheet diameter?

Avoid long ultrasonic treatment because ultrasonic power and time can reduce graphene oxide sheet diameter. Control dispersion temperature below 40 °C as per the handling guidance. The material is supplied as vacuum-dried sheets and should be stored dry and protected from light before dispersion.

What are the storage and shelf-life requirements for Atomfair large-diameter graphene oxide sheets?

Store the material dry and protected from light. The handling guidance states that unopened material should be stored for no more than 6 months. Avoid long ultrasonic treatment during processing to maintain sheet integrity.

Assessment

This large-diameter (>5 µm) graphene oxide sheet with 1-6 layers, prepared via modified Hummers method, offers significant flake size for GO research but requires careful handling to avoid sonication-induced diameter reduction and must be stored dry, protected from light, with a six-month shelf life unopened.

Positive

Large flake diameter >5 µm: Sheet diameter >5 µm supports applications requiring larger graphene oxide flakes, enabling better performance in films, composites, and membranes where flake size is critical.
Defined 1-6 layer structure: The controlled 1-6 layer range provides consistent nanosheet thickness and accessible oxygen functional groups for dispersion and chemical modification, facilitating downstream processing.

Trade-offs

Ultrasonic treatment sensitivity: Prolonged ultrasonic treatment can reduce sheet diameter; users must minimize sonication time and power to preserve flake size during dispersion.
Strict storage and shelf-life limits: Material must be stored dry and protected from light, with a maximum unopened shelf life of 6 months; dispersion temperature must be kept below 40 °C to avoid degradation.
