Abstract
Przedmiotem wynalazku jest sposób wytwarzania płatków grafenowych metodą elektrochemicznego złuszczania, gdzie elektrody (anoda i katoda) wraz z elektrolitem stanowią obwód elektrochemiczny przez który przepływa prąd, charakteryzujący się tym, że elektrody zanurza się przynajmniej częściowo w elektrolicie i prowadzi się elektrolizę w trakcie której płatki grafitu odrywają się od elektrody uwalniając się do roztworu elektrolitu, a następnie odzyskuje się złuszczone płatki grafenu z roztworu elektrolitu.
