Diatomite which is a weak material in natural form possesses dielectric behavior and low reactivity. A new preparation method of thermally reduced graphene oxide/diatomite composites with a segregated network structure is exhibited. 13 wt.% glass powder is mixed in the diatomite. The diatomite particles coated graphene oxide in situ thermal reduction make electrical conductive composites; the percolation threshold is 0.229 vol.%. At the same time, the highest compressive strength of diatomite increased from 11.3 to 21.1 MPa. (C) 2014 Elsevier B.V. All rights reserved.
