Research on the exfoliation of graphite oxide in alternating electric field

Chemical reduction of exfoliated graphite oxide has been considered as one attractive potential approach for large-scale production of graphene nanosheets,and its exfoliation step has a major influence on the quality of product.In this paper,alternating electric field was used to exfoliate graphite oxide into graphene oxide nanosheets.The result shows that the thickness and lateral size of the graphene oxide nanosheets decrease with increasing voltage,but increase with increasing frequency.If the voltage can satisfied the exfoliation of graphite oxide,the thickness and lateral size of the graphene oxide nanosheets decrease when distance between two graphite electrodes enlarged.
