Abstract
1. Способ модифицирования углеродных нанотрубок, включающий обработку углеродных нанотрубок водным раствором окислителя, отличающийся тем, что обработку углеродных нанотрубок водным раствором окислителя проводят одновременно с механической обработкой, причем, в качестве окислителя применяют раствор персульфата или гипохлорита при рН более 10.2. Способ по п.1, отличающийся тем, что механическую обработку проводят с помощью бисерной мельницы.3. Способ по п.1, отличающийся тем, что окислитель берут в количестве, эквивалентном от 0,1 до 1 г-атома активного кислорода на 1 г-атом углерода нанотрубок.4. Способ по п.1 или 3, отличающийся тем, что избыток гипохлорита к реакционной смеси при рН более 10 удаляют прибавлением перекиси водорода.1. A method of modifying carbon nanotubes, comprising treating carbon nanotubes with an aqueous solution of an oxidizing agent, characterized in that the processing of carbon nanotubes with an aqueous solution of oxidizing agents is carried out simultaneously with mechanical treatment, moreover, a solution of persulfate or hypochlorite is used as an oxidizing agent at a pH of more than 10.2. The method according to claim 1, characterized in that the machining is carried out using a bead mill. The method according to claim 1, characterized in that the oxidizing agent is taken in an amount equivalent to from 0.1 to 1 g-atom of active oxygen per 1 g-carbon atom of the nanotubes. The method according to claim 1 or 3, characterized in that the excess hypochlorite to the reaction mixture at pH greater than 10 is removed by the addition of hydrogen peroxide.
