中文摘要	different graphene inks have been synthesized by chemical methods. these uniform dispersions were stabilized by various functional groups such as room temperature ionic liquid, polyaniline, polyelectrolyte (poly[2,5-bis(3-sulfonatopropoxy)-1,4-ethynylphenylene-alt-1,4-ethynylphenylene] sodium salt) and poly(styrenesulfonate) (pss). the dispersions can be easily cast into high-quality, free-standing films but with very different physiochemical properties such as surface tension and adhesion. sem and afm methods have been applied to have a detailed study of the properties of the inks. it is found that graphenes modified by p-type polyaniline show the highest surface tension. diverse surface adhesive properties to the substrate are also found with various functional groups. the different viscoelasticities of graphene inks were related to the microscopic structure of their coating layer and subsequently related to the configuration, chemistry and molecular dimensions of the modifying molecules to establish the property-structure relationship. modifications of graphene inks made from chemical reduction cannot only enable cost-effective processing for printable electronics but also extend the applications into, for example, self-assembly of graphene via bottom-up nano-architecture and surface energy engineering of the graphenes. to fabricate useful devices, understanding the surface properties of graphene inks is very important. it is the first paper of this kind to study the surface tension and adhesion of graphene influenced by different functional groups.
