I prepared graphene oxide following the Stauddenmeir method but I changed the standard acid ratio. In result I got graphene oxide after 4 days which has interlayer distance above 11Å which more than the distance seen in graphene oxide normally.
Well, is interesting to know other thechiques to obtain a large interlayer d-spacing.
you can see other papers about that.... ACS nano, 5(2), 1253-1258 or Carbon, 63, 376-389.
Inter-layer spacing has no significance other than the bulk density and conductance.
Larger interlayer distance means a higher degree of exfoliation, thus the possibility to obtain less atomic layers which is interesting for applications -as TCE for example, where the interest is to get as few layers as possible keeping conductivity high-, mainly coming from a chemistry based method. In recent contribution the interlayer distance, that was related with the surface chemistry of GO, was related with the resistance, thus it will be interesting in your case to study both the surface chemistry (functional groups formed from your procedure) as well as the electrical conductivity.
