I want to find GO (dispersed in NMP) dielectric constant / permittivity , under DC field of about 3.7 V/mm
Can refer to Vector Network Analyzer (VNA) Measurements and Uncertainty Assessment Book by Nosherwan Shoaib
Or u can design your own VNA according to your demands

We can measure dielectric constants of suspended particles in liquid medium by using a liquid test fixture and a dielectric analyzer
thank you so much
I was looking for the same issue:
May be this experimental study on graphene/GO/graphene capacitors may be useful (surely you already found it): J. Liu, D. Galpaya, M. Notarianni, C. Yan, N. Motta, Appl. Phys. Lett. 2013, 103, 063108.
adding graphene oxide / rGO / graphene have shown conflicting surface roughness changes in Polyethersulfone. for rGO in specific, why do we have roughness decrease whilst porosity has increased?
