Pure Single-Walled Carbon Nanotube Film

Product Introduction

Pure Single-Walled Carbon Nanotube Film is a freestanding conductive film made of high-purity single-walled carbon nanotubes, available in water-based and solvent-based (oil-based) preparation versions. It features ultra-thin thickness, excellent mechanical strength, adjustable surface wettability and stable electrolyte resistance. This self-supporting carbon nanotube film can form a highly efficient conductive network without extra binder, widely used in new energy, electronic conduction and sensing fields.

Product Advantages

  1. Ultra-thin thickness range from 3 μm to 200 μm, lightweight with low areal density 5–15 g/m²
  2. Two production grades: water-based & oil-based, with differentiated mechanical modulus for different application demands
  3. Outstanding electrolyte tolerance, passes 24-hour electrolyte immersion test without swelling or failure
  4. Adjustable wetting angle from 30° to 120°, flexible matching with various slurry and electrolyte systems
  5. Superior electrical conductivity, excellent flexibility and fold resistance, can be processed into rolls or cut pieces
  6. Low impurity content, stable conductive performance under long-term working conditions

Product Functions

  1. Build continuous high-speed electron transmission network, reduce contact resistance of electrodes
  2. Serve as flexible conductive current collector or conductive interlayer for energy storage devices
  3. Realize customized surface wettability to optimize interface bonding with active materials
  4. Provide mechanical reinforcement for electrode structure, improve cell cycling stability
  5. Work as transparent/black conductive layer for flexible electronics, sensors and electromagnetic shielding

Product Application Scenarios

  • Lithium-ion / sodium-ion battery conductive layers, flexible electrode current collectors
  • Supercapacitors and other electrochemical energy storage devices
  • Flexible electronics, flexible sensors, electromagnetic shielding materials
  • Thermal conductive films, membrane electrode substrates

FAQ

What is the minimum order quantity (MOQ)?

Our standard MOQ is 1 kg for sample evaluation. For bulk orders, we recommend starting from 20 kg to enjoy better pricing and stable batch consistency.

Can you provide free samples for testing?

Yes, we can provide small free samples (typically 10–50 g) for initial evaluation. The courier cost is normally covered by the buyer, and it can be deducted from the first bulk order.

How should SWCNT powder be dispersed?

Due to their ultra-high aspect ratio and strong van der Waals forces, SWCNTs are much harder to disperse than conventional carbon black. We recommend using high-shear mixing, ultrasonic dispersion, or three-roll milling, combined with suitable surfactants or dispersants (such as NMP or specific polymers) to prevent agglomeration. To completely bypass the dispersion challenge, we also offer pre-dispersed water-based or NMP oil-based SWCNT conductive slurries for direct use in your production.

What is the lead time for bulk orders?

Samples can be shipped within 3–5 working days. For bulk orders, the lead time is usually 10–20 working days depending on quantity and customization requirements.

Do you support customized specifications?

Yes. We can customize purity, diameter, length, surface functionalization and packaging according to your application. Please contact us with your detailed requirements.
