Abstract
A method for treating carbon nanotubes is provided. In the method for treating carbon nanotubes (CNTs), the CNTs are treated with SO3 gas at an elevated temperature, for example, at a temperature in the range of 385° C. to 475° C.
Claims12
A method for treating carbon nanotubes (CNTs), comprising:
- treating the CNTs with sulfur trioxide gas at a temperature between 385° C. and 475° C. in an environment substantially without oxygen by pumping out to vacuum and backfilling with an inert gas to standard pressure prior to treatment.
A method for treating carbon nanotubes (CNTs), comprising:
- treating the CNTs with a nitrogen oxide gas at a temperature between 385° C. and 475° C. in an environment substantially without oxygen by pumping out to vacuum and backfilling with an inert gas to standard pressure prior to treatment.
A method for treating carbon nanotubes (CNTs), comprising:
- treating the CNTs with a planar molecular gas at a temperature between 385° C. and 475° C. in an environment substantially without oxygen by pumping out to vacuum and backfilling with an inert gas to standard pressure prior to treatment.
