I want to synthesize graphene oxide from graphite powder using Hammer's method, using so small particles instead bigger/flakes.
Yes , You Can ..........But the particle size will effect the quality of graphene. because smaller particles is more oxidized which means that oxidized more easily under the same conditions.Larger particles are hard to oxidized because of broken smaller pieces with defects.
A very good reference :
influence of grain size of precursor graphite on the synthesis of graphite oxide.
It is possible. But you have to consider particle size. It may effect your quality of GO. However, it so good, you can achieve smaller size.
Thank you very much guys, In my second attempt definitely I'll consider your suggestions...more oxidation in case of smaller particles, could be due to the larger over all surface area...
yes you can get smaller size of graphene oxide ....first start with expanding(interlayer spacing) by using HNO3 + H2SO4 (1:3) then synthesize graphite oxide by hummer's method. up to this stage you will get nearly ~ 70 layers of graphene oxide and then after thermal exfoliation (~1000 degree Celsius) so you can achieve up to 5-10 layer of graphene oxide . Remember there will be some defects also as like edge and point etc.
