摘要
The present invention relates to a composition containing graphene and grafene nanoplatelets durably dispersed in a solvent. Said composition is characterized in that it contains at least 1% by weight, with respect to the total weight of the solvent, of a vinyl aromatic polymer and comprises a mass concentration of graphene and graphene nanoplatelets (GRS) ranging from 0.001% to 10% by weight with respect to the total weight of the solvent. The vinyl aromatic polymer present in the composition is obtained by partial or total polymerization of the relative vinyl aromatic monomer alone or mixed with up to 50% by weight of further copolymerizable monomers. The composition must satisfy the condition that the sum of the possible content of non-reacted monomers and the content of vinyl aromatic polymer formed is equal to at least 10% by weight with respect to the total weight of the solvent.
