1
Independentpartly reduced graphenenanosubstance (conductive, particle/rod/cylinder/fiber, 0.3–100 nm diameter)linked stacks of partly reduced graphene
Linked stacks of partly reduced graphene comprising two or more stacks of partly reduced graphene linked together; wherein the stack of partly reduced graphene has two or more sheets of partly reduced graphene and a nanosubstance held between the sheets of partly reduced graphene; the partly reduced graphene has no carbonyl groups and has carboxyl groups and hydroxyl groups; and diﬀerent stacks of partly reduced graphene are linked to each other by an ester bond.
1. 2
  Dependent← claim 1nanosubstance (conductive, particle/rod/cylinder/fiber, 0.3–100 nm diameter)
  The linked stacks of partly reduced graphene according to claim 1, wherein the nanosubstance comprises a conductive material and is a particle, a rod-like body, a cylindrical body or a ﬁbrous body with a diameter of 0.3 nm or more and 100 nm or less.
2. 5
  Dependent← claim 1partly reduced graphene
  The linked stacks of partly reduced graphene according to claim 1, wherein a plurality of the stacks of graphene are linked together in either or both of a parallel direction and a perpendicular direction to a sheet plane of the reduced graphene.
