Research Grade Single-walled Carbon Nanotubes Application
This product is produced by methane catalytic decomposition over co-based catalyst, then experienced deep air oxidation. There is almost no amorphous carbon in this product.  It has high ignition temperature, 610 ~ 620°C.  It can be used to make transparent conductive films and other research & industrial application.  This SWNTs-based Transparent Conductive Films can reach less than 200 ohm/sq sheet resistance with more than 80% transparency. The product is the ideal manufacturing material for CNT-based Transparent Conductive Films for the touch screen, flat panel display, OLED, and thin-film solar industries.  Compared with traditional indium tin oxide (ITO) coated films, the CNT-based transparent Conductive Films have the evidently superiority as follows: (1) More mechanical robustness for longer lifetime; (2) The broader and more color-neutral transmittance; (3) Reaching higher levels of sheet resistance without losing uniformity; (4) lower cost.

How to disperse CNTs: 
Order CNTs Alcohol Dispersant -- US4496
Order CNTs Ester Dispersant -- US4497
Order CNTs Water Dispersant -- US4498      
Example - Using US4498 dispersant to disperse CNTs:
1) Single-walled: US4498 should be 3 to 4 times of carbon tubes;
2) Multi-walled: US4498 should be 0.1 to 4 times of carbon tube (corresponding diameter descending)
3)  Step 1, add US4498 into water first. Step 2, when US4498 fully dissolved into water, then add CNTs. Step 3, finally subjected to ultrasonic (this requires the customer's own experience).  Order CNTs Dispersion Products
