Проводящие свойства одностенных углеродных нанотрубок в композитах на основе полистирола

Аннотация
Композитные пленки синтезированы методом радикальной сополимеризации стирола с метакрилатными группами на поверхности модифицированных одностенных углеродных нанотрубок. Их механическое измельчение и переформовка на поверхности электродов привели к снижению значений сопротивления отдельных участков поверхности на 2 порядка. Данный эффект наблюдался при измерении вольт-амперных характеристик как сэндвич-, так и планарных металл/полимерный композит/металл структур. Такое снижение сопротивления локальных участков композитных пленок, вероятно, связано с измельчением и переориентацией углеродных нанотрубок, а также изменением механических напряжений между ними и полимерной матрицей в ходе проделанных манипуляций, что могло повлиять на электронную структуру включений углеродных нанотрубок.
