GRAPHENE PARTICLE DETECTION METHOD WHICH ISOLATES GRAPHENE OXIDE NANO PARTICLES OR REDUCED GRAPHENE NANO PARTICLES FROM A SOLUTION BY USING MICROBUBBLES

摘要

PURPOSE: A graphene particle detection method is provided to be simpler than existed nanoparticle detection method which uses coagulant and centrifugation and to easily detect and manufacture graphene oxide and reduced graphene nanoparticles.;CONSTITUTION: A graphene particle detection method comprises the following steps: performing reaction by injecting graphite particles into a container which contains one of acid or basic liquids; peeling off the graphite particles by using graphene sludge including graphene oxide and graphene particles; injecting micro bubbles in order to separate graphene oxide and graphene particles which are remained as sludge; floating and isolating the graphene oxide and graphene particles by reacting the micro bubbles with sludge; and collecting the graphene oxide and the graphene particles isolated from slurry.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Graphite; (BB) Acid, base solution; (CC) Exfoliate graphite particles; (DD) Graphite sludge containing graphene oxide particles; (EE,LL) Floating separation; (FF) Graphene oxide; (GG,NN) Collection; (HH) Air; (II) Reducing process; (JJ) Nozzle; (KK) Graphene particles; (MM) Graphene
