HCID 24681Fuming sulfuric acid

Procedure

A dispersion was prepared, as described in Example 1, except substituting oleum for chlorosulfonic acid. A known volume of the dispersion was passed through a 0.2 μm Anodisc membrane, with vacuum assistance, to create the initial CNT network of desired thickness. Approximately, 50 mL of diethyl ether was added as a non-solvent, while maintaining vacuum. The SWNT network film was released from the membrane filter by dipping the coated membrane filter into a water bath. The SWNT network film floated to the surface of the water and was picked up with a substrate such as polyester or glass.
