A method for functionalizing the sidewalls of HiPco SWNT via interaction with carbon‐ and metal‐centered radicals is presented. A number of methods: UV‐vis‐NIR spectroscopy, thermogravimetric analysis, TEM and Raman spectroscopy provided a direct evidence of a chemical attachment of functional groups to the tubes. Functionalization was shown to be reversible: a thermal treatment led to the recovering of pristine structure of SWNT.
