Avaliação das técnicas de dispersão mecânica e ultrassônica de nanotubos de carbono de paredes múltiplas em resina epóxi
(2014-06-03)
In this study nanotubes/epoxy composites were produced in order to evaluate which of the two studied techniques would result in a better degree of dispersion and unentanglement of carbon nanotubes in epoxy resin. The ...
