Three different SP treatment time durations of 5, 10, and
15 min were applied as the experimental parameter to a sample solution including graphite in 9% hydrogen peroxide (H2O2) aqueous solution. The
prepared graphene derivatives showed high dispersibility in contrast to that from natural graphite. The average particle size and absolute value of
zeta potential of the obtained samples decreased as the SP treatment time increased. The particle size of SP-treated graphene derivatives in the
supernatant linearly decreased depending on the SP treatment duration. The required particle size between 1.6 and 2.5μm was obtained by SP
treatment (i.e., reaction control was achieved). It was clearly shown that the necessary reaction time for graphene treatment using SP processing
was much shorter than that by the modified Hummers method.英語フィールド
