Overview
XFNANO (先丰纳米) is a Nanjing-based high-tech enterprise founded in 2009, specializing in the research, production, and distribution of nanomaterials. The company has established itself as a key supplier in the global nanotechnology market, serving over 10,000 clients across 50+ countries. XFNANO's product lines encompass graphene oxide, carbon nanotubes, quantum dots, and metal nanoparticles, all characterized by high purity (up to 99.9%) and customizable specifications. The company operates a 20,000 m² production facility with ISO 9001-certified quality control systems. XFNANO collaborates closely with academic institutions, holding 100+ patents in nanomaterial synthesis and application technologies. Its products are widely adopted in cutting-edge industries, from flexible electronics to advanced catalysis.
Physical and Chemical Properties
XFNANO's nanomaterials exhibit unique properties derived from their nanoscale dimensions and tailored surface chemistry. Graphene products, for instance, demonstrate exceptional electrical conductivity (up to 10^6 S/m) and mechanical strength (130 GPa tensile strength). Carbon nanotube variants show aspect ratios from 100–10,000 with tunable wall numbers (SWCNT to MWCNT). Metal nanoparticles (e.g., Ag, Au) are available in 5–100 nm sizes with controlled crystallinity. Surface functionalization options include carboxylation, hydroxylation, and amination, enabling compatibility with diverse matrices. The materials typically have high specific surface areas (e.g., 500–1500 m²/g for activated graphene) and show quantum confinement effects. Thermal stability varies by material, with most carbon-based products stable below 400°C in air and higher in inert atmospheres.
Main Applications
In electronics, XFNANO's materials enable transparent conductive films for touchscreens and flexible circuits, with sheet resistances as low as 100 Ω/sq. The energy sector utilizes them in lithium-ion battery anodes (capacity up to 1000 mAh/g) and supercapacitor electrodes. Composite materials incorporate these nanomaterials to enhance mechanical strength (30–300% improvement) while reducing weight. Biomedical applications include drug delivery vectors (functionalized nanotubes) and biosensors (graphene FET platforms). Coatings benefit from antimicrobial properties (Ag nanoparticles) and UV resistance. Emerging uses span 3D printing filaments, thermal interface materials, and hydrogen storage systems. Research institutions employ XFNANO products for fundamental studies in nanotechnology and materials science.
Safety and Storage
Dry powder forms require handling in fume hoods with N95 respirators due to nanoparticle inhalation risks. Eye protection and nitrile gloves are mandatory to prevent dermal exposure. Storage must prevent moisture absorption (desiccators recommended) and oxidation (argon packaging for sensitive materials). Spills should be addressed with HEPA-filter vacuums, never dry sweeping. Material Safety Data Sheets (MSDS) accompany all products, detailing specific hazards. Carbon-based materials are generally stable but may combust at high temperatures (>400°C) in powder form. Dispersions require agitation before use and have limited shelf lives (typically 6 months). Transportation complies with IATA/IMDG regulations for hazardous materials where applicable.
B2B Procurement Guide
For bulk procurement (1 kg+), XFNANO offers 15–30% discounts with MOQs varying by product. Custom synthesis services require 4–8 weeks lead time for new formulations. Key specifications to confirm include purity (99% vs. 99.9%), particle size distribution (D50/D90 values), and surface area (BET method). Sample quantities (1–10g) are available for R&D validation. Payment terms typically involve 30% deposit with balance before shipment. OEM/private labeling is possible for orders exceeding 5 kg. Importers should verify local regulations—some nanomaterials require special permits in the EU (REACH) and North America (EPA/TSCA). Technical support includes application guidance and characterization reports (TEM, XRD, Raman).
