▎ 摘  要

NOVELTY - Use of polyalkylene oxides which have at least one aromatic radical as a dispersant for graphene material. USE - The polyalkylene oxide is useful as dispersant for graphene material. ADVANTAGE - The polyalkylene oxide has improved electrical conductivity, improved thermal conductivity, reduced friction, improved mechanics, increased scratch resistance, good radiation absorption, good antibacterial/antiviral effect, improved flame protection and reduced gas permeability. DETAILED DESCRIPTION - INDEPENDNET CLAIMS are also included for: method for dispersing graphene material, comprising polyalkylene oxides used as dispersing agent; and composition, comprising a continuous phase, a dispersing agent, and graphene material.
