1) Purpose
This SOP outlines the procedure for preparing carbon-based nanomaterials, such as graphene, carbon nanotubes, and fullerenes, which are used in various applications including drug delivery, electronics, and energy storage.
2) Scope
This SOP applies to personnel involved in the synthesis and characterization of carbon-based nanomaterials for research or industrial purposes.
3) Responsibilities
- Operators: Responsible for synthesizing carbon-based nanomaterials and performing quality control tests.
- QA: Ensures that the nanomaterials meet the required specifications for purity, particle size, and structure.
4) Procedure
4.1 Synthesis of Carbon Nanomaterials
4.1.1 Chemical Vapor Deposition (CVD) Method
- 4.1.1.1 Use the CVD method to synthesize graphene or carbon nanotubes by depositing carbon atoms onto a substrate through the thermal decomposition of a carbon source (e.g., methane).
4.1.2 Arc Discharge Method
- 4.1.2.1 Alternatively, use the arc discharge method to synthesize fullerenes or multi-walled carbon nanotubes by vaporizing carbon electrodes in an inert atmosphere.
4.2 Purification and Characterization
4.2.1 Purification
- 4.2.1.1 Purify the synthesized carbon nanomaterials using acid treatments or thermal oxidation to remove any impurities or catalyst residues.
4.2.2 Characterization
- 4.2.2.1 Characterize the nanomaterials using techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Raman spectroscopy to determine their structure, purity, and size.
4.3 Stability and Storage
4.3.1 Stability Testing
- 4.3.1.1 Conduct stability studies under different environmental conditions (e.g., temperature, humidity) to assess the long-term stability of the nanomaterials.
4.3.2 Storage Conditions
- 4.3.2.1 Store the carbon-based nanomaterials in sealed, dry containers at room temperature to prevent oxidation or degradation.
