Large-Diameter Graphene Oxide Sheet, 1 g

Product Type: Graphene Oxide Sheet
Research-grade laboratory product

Product Overview

Large-diameter graphene oxide sheet with >5 µm sheet diameter and 1-6 layer structure supports GO research where larger flake size, surface functional groups and sheet-form handling are important selection factors.

The material provides oxygen-functionalized graphene oxide prepared by a modified Hummers route and vacuum drying, with stated guidance to avoid long ultrasonic treatment and store dry away from light.

Performance Features
  • >5 µm sheet diameter supports large-flake graphene oxide applications.
  • 1-6 layer structure provides a defined nanosheet layer range.
  • Oxygen functional groups support dispersion and chemical modification.
  • Storage guidance supports dry, light-protected handling before dispersion.

This document outlines storage and dispersion constraints for the graphene oxide sheet. It specifies environmental conditions and processing limits to prevent material degradation.

  • Storage condition: Store the material dry and protected from light to maintain stability.
  • Dispersion temperature limit: Control dispersion temperature below 40 °C to prevent degradation.
  • Ultrasonic treatment limitation: Avoid prolonged ultrasonic treatment because it can reduce sheet diameter.
  • Shelf-life constraint: Use unopened material within 6 months of receipt.

These steps describe safe and effective handling of the graphene oxide sheet for dispersion. Follow them to preserve sheet integrity and avoid degradation.

  1. Store material
    Store the graphene oxide sheet in a dry, light-protected environment.
  2. Prepare dispersion
    Transfer the material to a suitable solvent while keeping the temperature below 40 °C.
  3. Minimize sonication
    Limit ultrasonic treatment time to avoid reducing the sheet diameter.
  4. Check shelf life
    Confirm the material is used within 6 months when stored unopened.

What are the critical handling precautions to prevent flake size reduction during processing of this large-diameter graphene oxide sheet?

Avoid long ultrasonic treatment because ultrasonic power and time can reduce sheet diameter below the >5 µm specification. Control dispersion temperature below 40 °C and store the material dry and protected from light. Unopened material should be used within 6 months as stated in the handling guidance.

What storage conditions and shelf life are recommended for maintaining the integrity of this graphene oxide sheet?

Store dry and protected from light to preserve the oxygen-functionalized structure. The material is vacuum-dried and should be kept unopened for no more than 6 months. Dispersion temperature must be controlled below 40 °C during use to avoid degradation.

This large-diameter graphene oxide sheet (>5 µm, 1-6 layers) prepared by modified Hummers method offers oxygen-functionalized nanosheets suitable for dispersion and chemical modification, but requires careful handling to avoid ultrasonic degradation and strict dry, light-protected storage with a 6-month shelf life.

Positive

  • Large sheet diameter >5 µm: The >5 µm sheet diameter supports large-flake graphene oxide applications where flake size is critical for performance.
  • Oxygen functional groups for modification: Oxygen functional groups on the sheets enable effective dispersion in solvents and provide sites for chemical modification, facilitating downstream processing and functionalization.

Trade-offs

  • Ultrasonic treatment sensitivity: Prolonged ultrasonic treatment can reduce sheet diameter; users must avoid long sonication to maintain the large-flake structure.
  • Stringent storage requirements: The material must be stored dry and protected from light, with dispersion temperature kept below 40 °C and unopened shelf life limited to 6 months as per handling guidance.
