Изобретение относится к нанотехнологии. Способ получения углеродного нанокристаллического материала включает приготовление раствора полиакрилонитрила (ПАН) (Мη=1×105) в диметилформамиде (ДМФА) с СПАН=1÷5 мас.%, выдерживание ПАН до растворения в ДМФА в течение 72 часов при 25°С, нанесение на стеклоуглеродную основу слоя раствора ПАН/ДМФА, сушку полимерного слоя в сушильном шкафу при 90°С в течение 0,5÷1 час, нагрев пленки полимера со скоростью 2÷20°С/мин под действием ИК-излучения и выдержку пленки более 1 секунды при 800÷900°С, Р=10-3 мм рт.ст. Изобретение позволяет получать углеродный нанокристаллический материал, чувствительный к рН среды. 1 табл., 2 ил. |
