General introduction
Some embodiments provide the piece of the perforated sheet including graphene-based material.Perforation can be located at graphene base material
Described of material is more than on 10% or the area more than 15%.In other embodiments, perforation field can correspond to
0.1% or bigger of the area of the piece of the graphene-based material.In a further embodiment, the average pore of perforation
Size can be selected from 0.3nm to 1 μm.At least one lateral dimension of described can be more than 1mm, more than 1cm or more than 3cm.
Some embodiments provide the perforated sheet of graphene-based material, and the graphene-based material is included before perforation
Single-layer graphene, the perforated sheet of graphene-based material include multiple perforation, it is characterised in that the perforation can be located at the stone
