Graphene oxide More Info
Graphene oxide (GO) is a single-layer or few-layer oxidized derivative of graphene, featuring oxygen-containing functional groups (hydroxyl, epoxy, carboxyl) on its surface. As a versatile chemical intermediate and functional material, it’s widely used across industries, with strong demand in global chemical trade.
Key Properties
Structure & Form: Thin, flexible sheet-like structure; typically supplied as powder, aqueous dispersion, or film.
Solubility: Easily dispersible in water and polar solvents (e.g., ethanol, NMP) – a key advantage over pristine graphene for processing.
Chemical Reactivity: Functional groups enable easy modification (e.g., reduction to reduced graphene oxide/rGO, grafting with polymers) for tailored properties.
Physical Traits: High surface area, good mechanical strength, and excellent thermal/electrical conductivity (enhanced after reduction).
Main Applications (High-Demand Sectors)
Composite Materials: Reinforcing agent for polymers, resins, rubber, and coatings (improves strength, barrier properties, and conductivity). Used in automotive parts, aerospace components, and anti-corrosion coatings.
Electronics & Energy: Electrode material for batteries (lithium-ion, supercapacitors), sensors, and flexible electronics (after reduction to rGO).
Biomedical & Water Treatment: Drug delivery carriers, biosensors, and adsorbents for heavy metal ions/wastewater purification (due to biocompatibility and high adsorption capacity).
Coatings & Adhesives: Antistatic, antibacterial, or barrier coatings for packaging, textiles, and industrial surfaces.
Trade & Technical Specifications
Purity: Typically 99.0%+ (metal impurities <100 ppm for high-end applications).
Layer Count: 1–5 layers (critical for performance; tested via AFM/TEM).
Dispersion Concentration: 0.5–5.0 wt% (aqueous or solvent-based, stable for 6+ months).
Particle Size: 0.5–5 μm (customizable for specific uses like composites or coatings).
Key Standards: Complies with ISO, ASTM, or REACH (EU) regulations; RoHS-compliant for electronics.
Market Trends
Growing Demand: Driven by electronics (EV batteries, supercapacitors) and composite materials – global market expected to reach $3.5B by 2028.
Regional Hotspots: Major consumers include China, the US, Germany, and South Korea; Asia-Pacific leads in production and demand.
Price Range: $50–$500/kg (varies by purity, layer count, and form; bulk orders for industrial use offer lower prices).
Key Suppliers: BASF, XFNANO, Graphenea, and Chinese manufacturers (e.g., Ningbo Morsh, Suzhou Tanfeng).
Trade Notes
Packaging: Powder supplied in vacuum-sealed aluminum foil bags (10g–1kg); dispersions in HDPE bottles (1L–20L) or IBC tanks (for bulk).
Storage: Store in cool, dry conditions (avoid direct sunlight); dispersions require gentle agitation before use.
Regulations: REACH (EU) and TSCA (US) list GO as a non-hazardous chemical, but proper labeling for transportation (UN3077 for aqueous dispersions) is required.
